Book excerpt: We consider the Hamiltonian for neutrino oscillations in matter in the case of arbitrary potentials including off-diagonal complex terms. We derive the expressions for the corresponding Hamiltonian in the basis of the instantaneous eigenstates in matter, in terms of quantities one can derive from the flavor-basis Hamiltonian and its derivative, for an arbitrary number of neutrino flavors. We make our expressions explicit for the two-neutrino flavor case and apply our results to the neutrino propagation in core-collapse supernovae where the Hamiltonian includes both coupling to matter and to neutrinos. We show that the neutrino flavor evolution depends on the mixing matrix derivatives involving not only the derivative of the matter mixing angles but also of the phases. In particular, we point out the important role of the phase derivatives, that appear due to the neutrino-neutrino interaction, and show how it can cause an oscillating degeneracy between the diagonal elements of the Hamiltonian in the basis of the eigenstates in matter. Lastly, our results also reveal that the end of the synchronization regime is due to a rapid increase of the phase derivative and identify the condition to be fulfilled for the onset of bipolar oscillations involving both the off-diagonal neutrino-neutrino interaction contributions and the vacuum terms.

Book Synopsis Open Issues in Core Collapse Supernova Theory by : Anthony Mezzacappa
Download or read book Open Issues in Core Collapse Supernova Theory written by Anthony Mezzacappa and published by World Scientific. This book was released on 2005 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts to uncover the explosion mechanism of core collapse supernovae and to understand all of their associated phenomena have been ongoing for nearly four decades. Despite this, our theoretical understanding of these cosmic events remains limited; two- and three-dimensional modeling of these events is in its infancy. Most of the modeling efforts over the past four decades have, by necessity, been constrained to spherical symmetry, with the first two-dimensional, albeit simplified, models appearing only during the last decade. Simulations to understand the complex interplay between the turbulent stellar core fluid flow, its magnetic fields, the neutrinos produced in and emanating from the proto-neutron star, the stellar core rotation, and the strong gravitational fields have yet to be performed. Only subsets of these fundamental ingredients have been included in the models thus far, often with approximation.The purpose of this volume is to identify the outstanding issues that remain in order to come to a complete understanding of these important astrophysical events. As the book focuses on open issues rather than the current state of the art in the field ? although the latter will certainly be discussed ? it will remain relevant for some time.
Book Synopsis Effects of Non-standard Neutrino Flavor Changing Interactions in Core Collapse Supernovae by : Philip Amanik
Download or read book Effects of Non-standard Neutrino Flavor Changing Interactions in Core Collapse Supernovae written by Philip Amanik and published by . This book was released on 2006 with total page 89 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-standard neutrino flavor changing interactions are included in the core collapse supernova model, and their effects on the model are investigated. Analytical and numerical results are presented. The predictions from a model that includes the new neutrino interactions are found to be different from the predictions of the original model. The non-standard interactions are predicted by some extensions to the standard model, but no such interactions have been discovered or proven to exist. An example of an interaction which comes from R-parity violating Supersymmetry is discussed in detail in Chapter 1. Reviews of nuclear physics and the supernova model are also given in this chapter. The cross sections for neutrino flavor changing scattering in vacuum with nuclei and free nucleons are given in Chapter 1. Corrections which account for neutrinos scattering with nuclei in the core medium are given in Chapter 2. Uncertainties in the equation of state and composition of nuclear matter at high density, and the impact of these uncertainties on neutrino scattering cross sections are discussed in Chapter 2 as well. Analytical estimates of flavor changing scattering rates are calculated in Chapter 1 and a qualitative discussion of the effects on the model is then offered. Results from a one-zone core collapse numerical simulation are presented in Chapter 2. A detailed discussion of the code, and equations which describe the core are included in this chapter. Chapter 3 outlines how to include these interactions in a full simulation with neutrino transport and hydrodynamics.

Book Synopsis The Phenomenology of Neutrino Oscillations in Cosmology and Core-collapse Supernovae by : Lucas Andrew Johns
Download or read book The Phenomenology of Neutrino Oscillations in Cosmology and Core-collapse Supernovae written by Lucas Andrew Johns and published by . This book was released on 2020 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrinos have shaped cosmic history in important ways. In early epochs, they left their mark on the expansion of the universe and the genesis of primordial nuclei. In more recent eras, their signature has been repeatedly etched into the explosive dynamics of massive stars and the chemical enrichment of the cosmos. In the guise of sterile neutrinos, they may even constitute the dark matter. None of these roles is, as of yet, fully understood. Aside from the observational challenges, there are significant theoretical ones. Neutrinos are known to come in at least three different flavors, each of which interacts differently with other particles. They are also known to oscillate: due to quantum mechanics, a neutrino's flavor changes in the course of its propagation. The phenomenology that emerges in dense neutrino systems as a result of flavor oscillations is a frontier topic of precision cosmology and high-energy astrophysics. It is the focal point of this dissertation. The central theme is nonlinearity. When a system is dense in neutrinos, kinetic behaviors can arise that differ dramatically from those in systems dense only in "ordinary" matter like electrons and nucleons. The key piece of microphysics in this regard is the forward scattering of neutrinos on one another, which causes the flavor evolution of any given neutrino to depend on the flavor states of all neutrinos that it crosses paths with. The chapters here explore some of the macroscopic consequences of this subtle quantum phenomenon, with applications to the lepton-asymmetric early universe, core-collapse supernovae, and sterile neutrino dark matter.
Book Synopsis Neutrino Interactions with Nuclei and Dark Matter by : Paraskevi C. Divari
Download or read book Neutrino Interactions with Nuclei and Dark Matter written by Paraskevi C. Divari and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Even though the combined laboratory, astrophysical and cosmological evidence implies that neutrinos have masses, neutrinos provide only a small cosmic dark matter component. The study of solar neutrinos provides important information on nuclear processes inside the Sun as well as on matter densities. Moreover, supernova neutrinos provide sensitive probes for studying supernova explosions, neutrino properties and stellar collapse mechanisms. Neutrino-nucleus reactions at energies below 100 MeV play essential roles in core-collapse supernovae, explosive and r-process nucleosynthesis, as well as observation of solar and supernova neutrinos by earthbound detectors. On the other hand, recent experimental data of high-energy extragalactic neutrinos at 1 PeV open a new window to probe non-standard neutrino properties, such as resonant effects in the oscillation probability.
Book Synopsis Measurements of Neutrino Mass by : F. Ferroni
Download or read book Measurements of Neutrino Mass written by F. Ferroni and published by IOS Press. This book was released on 2009-09-29 with total page 493 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume offers a valuable insight into various aspects of the ongoing work directed at measuring neutrino mass. It took twenty years to refute the assertions of Bethe and Peierls that neutrinos were not observable, but it has since been realised that much can be learnt from these particles. The moral is, as Fiorini argues here, that the study of neutrinos was and remains demanding but rewarding. Subjects addressed in this volume include; clarifying the meaning of the Klapdor-Kleingrothaus results, probing the Majorana nature of neutrinos, observing lepton number violating effects for the first time, studying the end point of the spectrum in the search for neutrino masses and speculating whether it is possible to measure neutrino masses in cosmology. Lectures are enriched with rich historical overviews and valuable introductory material. Attention is also given to theoretical topics such as the evolution of the concept of mass in particle physics, a status report on neutrino oscillations and current discussion on neutrino masses. The reader is further reminded that neutrino masses may also have some bearing on the very origin of the matter among us, and have many deep links with other important lines of current physics research.
Book Synopsis Identification of Nuclear Effects in Neutrino-carbon Interactions at Low Three-momentum Transfer by :
Download or read book Identification of Nuclear Effects in Neutrino-carbon Interactions at Low Three-momentum Transfer written by and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two different nuclear-medium effects are isolated using a low three-momentum transfer subsample of neutrino-carbon scattering data from the MINERvA neutrino experiment. The observed hadronic energy in charged-current [nu][mu] interactions is combined with muon kinematics to permit separation of the quasielastic and [Delta](1232) resonance processes. First, we observe a small cross section at very low energy transfer that matches the expected screening effect of long-range nucleon correlations. Second, additions to the event rate in the kinematic region between the quasielastic and [Delta] resonance processes are needed to describe the data. The data in this kinematic region also have an enhanced population of multiproton final states. Contributions predicted for scattering from a nucleon pair have both properties; the model tested in this analysis is a significant improvement but does not fully describe the data. We present the results as a double-differential cross section to enable further investigation of nuclear models. Improved description of the effects of the nuclear environment are required by current and future neutrino oscillation experiments.
Book Synopsis Sixty Years Of Double Beta Decay: From Nuclear Physics To Beyond Standard Model by : Hans Volker Klapdor-kleingrothaus
Download or read book Sixty Years Of Double Beta Decay: From Nuclear Physics To Beyond Standard Model written by Hans Volker Klapdor-kleingrothaus and published by World Scientific. This book was released on 2001-04-30 with total page 1313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear double beta decay is one of the most promising tools for probing beyond-the-standard-model physics on beyond-accelerator energy scales. It is already now probing the TeV scale, on which new physics should manifest itself according to theoretical expectations. Only in the early 1980s was it known that double beta decay yields information on the Majorana mass of the exchanged neutrino. At present, the sharpest bound for the electron neutrino mass arises from this process. It is only in the last 10 years that the much more far-reaching potential of double beta decay has been discovered. Today, the potential of double beta decay includes a broad range of topics that are equally relevant to particle physics and astrophysics, such as masses of heavy neutrinos, of sneutrinos, as SUSY models, compositeness, leptoquarks, left-right symmetric models, and tests of Lorentz symmetry and equivalence principle in the neutrino sector. Double beta decay has become indispensable nowadays for solving the problem of the neutrino mass spectrum and the structure of the neutrino mass matrix — together with present and future solar and atmospheric neutrino oscillation experiments. Some future double beta experiments (like GENIUS) will be capable to be simultaneously neutrino observatories for double beta decay and low-energy solar neutrinos, and observatories for cold dark matter of ultimate sensitivity.This invaluable book outlines the development of double beta research from its beginnings until its most recent achievements, and also presents the outlook for its highly exciting future.
Book Synopsis Neutrino Flavor Instabilities in a Time-dependent Supernova Model by :
Download or read book Neutrino Flavor Instabilities in a Time-dependent Supernova Model written by and published by . This book was released on 2015 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, a dense neutrino medium such as that inside a core-collapse supernova can experience collective flavor conversion or oscillations because of the neutral-current weak interaction among the neutrinos. This phenomenon has been studied in a restricted, stationary supernova model which possesses the (spatial) spherical symmetry about the center of the supernova and the (directional) axial symmetry around the radial direction. Recently it has been shown that these spatial and directional symmetries can be broken spontaneously by collective neutrino oscillations. In this letter we analyze the neutrino flavor instabilities in a time-dependent supernova model. Our results show that collective neutrino oscillations start at approximately the same radius in both the stationary and time-dependent supernova models unless there exist very rapid variations in local physical conditions on timescales of a few microseconds or shorter. Our results also suggest that collective neutrino oscillations can vary rapidly with time in the regimes where they do occur which need to be studied in time-dependent supernova models.

This book was released on 2022-03-28 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the interdisciplinary areas of nuclear physics, supernovae and neutron star physics. It addresses the physics and astrophysics of the spectacular supernova explosions, starting with the collapse of massive stars and ending with the birth of neutron stars or black holes. Recent progress in the understanding of core collapse supernova (CCSN) and observational aspects of future detections of neutrinos from CCSN explosions are discussed. The other main focus in this text is the novel phases of dense nuclear matter, its compositions and equation of state (EoS) from low to very high baryon density relevant to supernovae and neutron stars. The multi-messenger astrophysics of binary neutron star merger GW170817 and its relation to EoS through tidal deformability are also presented in detail. The synthesis of elements heavier than iron in the supernova and neutron star environment by the rapid (r)-process are treated here with special emphasis on the nucleosynthesis in the ejected material from GW170817. This monograph is written for graduate students and researchers in the field of nuclear astrophysics.
