Book excerpt: With high-intensity neutrino beams and large mass detectors, neutrino physics has entered the high precision measurement era. Accelerator experiments that use highintensity proton beams impinging on a fixed target could produce dark matter along with neutrinos. DUNE, one of the most extensive neutrino experiments under construction, has similar prospects of looking for low-mass dark matter (LDM) produced in the proton interactions with the target. With the possibility of charge-neutral LDM production in the target, numerous neutrinos will be generated alongside it, which will be the primary background to the LDM signal. To understand these neutrino backgrounds, we studied two “modified DUNE” frameworks: Neutral Rich Horn Focusing (NRHF) System and Targetless DUNE. These systems help us reduce background neutrinos in search of LDM signals. These configurations also enhance the signal-to-background ratio by several orders of magnitude.

Book Synopsis Indirect Dark Matter Search with Neutrinos in JUNO and THEIA by : David Samuel Blum
Download or read book Indirect Dark Matter Search with Neutrinos in JUNO and THEIA written by David Samuel Blum and published by . This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive evidence from various astrophysical observations suggests that most of the matter in the universe is dark matter. However, the nature of dark matter is still unknown and remains one of the most prominent unanswered questions in physics today. A potential way to search for dark matter is the indirect dark matter search with neutrinos. It is based on the hypothesis that dark matter particles self-annihilate into neutrinos. This would result in a neutrino flux, which could be measured by neutrino detectors at Earth. In case of no excess signal is observed, a limit on the dark matter self-annihilation cross section can be set. The future neutrino detectors JUNO and THEIA can search for dark matter, especially for light dark matter particles with masses ranging from MeV to GeV. The search for such light dark matter particles has gained in importance in the last years as it extends the typical WIMP search to the sub-GeV mass range. In this work, the sensitivities of JUNO and THEIA to measure neutrinos from dark matter self-annihilation in the Milky Way as an excess over backgrounds are determined in detail for the first time. The work focuses on direct self-annihilation of light dark matter particles with masses ranging from 15 MeV to 100 MeV into neutrino-antineutrino pairs. The expected electron antineutrino signal measured through the inverse beta decay (IBD) reaction and all background contributions occurring in the visible energy region from 10 MeV to 100 MeV are determined for both detectors. To effectively reduce IBD-like background events of atmospheric neutrinos interacting via neutral current and of fast neutrons in JUNO, pulse shape discrimination is studied and applied in this work. THEIA would feature the separate measurement of Cherenkov and scintillation light. As a consequence, selection cuts on the ratio of measured Cherenkov to scintillation light and on the number of reconstructed Cherenkov rings are determined in this work, which can suppress atmospheric neutral current and fast neutron background events in THEIA with high efficiency. The sensitivities of JUNO and THEIA are determined using a Bayesian analysis and Markov Chain Monte Carlo sampling for dark matter masses ranging from 15 MeV to 100 MeV. JUNO will achieve the highest sensitivity for indirect dark matter search with neutrinos among existing neutrino detectors and will take a leading role in the indirect dark matter search in the upcoming years. The results of this work show for the first time that JUNO will improve the best currently existing 90 % C.L. upper limit of neutrino detectors on the dark matter self-annihilation cross section by a factor of 2 to 9 for 10 years of data taking. JUNO's potential to discover an electron antineutrino signal from dark matter self-annihilation in the Milky Way as an excess over backgrounds will be between 3 sigma and 5 sigma for most dark matter masses from 15 MeV to 100 MeV assuming an annihilation cross section that corresponds to the 90 % C.L. upper limit on the annihilation cross section of Super-K. This work moreover demonstrates that THEIA, if realized, could achieve a sensitivity comparable to JUNO.

Book Synopsis Neutrino Physics by : Hans V. Klapdor
Download or read book Neutrino Physics written by Hans V. Klapdor and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutrinos play an intriguing role in modern physics linking central questions of particle physics, cosmology and astrophysics. The contributions in this book reflect the present status of neutrino physics with emphasis on non-accelerator or beyond-accelerator experiments. Since a nonvanishing neutrino mass would yield an important boundary condition for GUT, SUSY or Superstring models and since neutrinos are the best candidates for dark matter in the universe, the many efforts to look for a neutrino mass, ranging from neutrino oscillation experiments using reactors, accelerators or the sun as neutrino sources, to tritium decay experiments and the search for neutrinoless double beta decay, are described in some detail. One of the sections is devoted to neutrinos from collapsing stars, including the supernova SN 1987 A. Possibilities for detecting cosmological neutrinos are discussed and an outlook to future experiments is given.
Book Synopsis Low Temperature Detectors for Neutrinos and Dark Matter by : Norbert Schmitz
Download or read book Low Temperature Detectors for Neutrinos and Dark Matter written by Norbert Schmitz and published by Springer. This book was released on 1987-09-30 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the last few years astrophysicists and elementary particle physicists have been working jointly on the following fascinating phenomena: 1. The solar neutrino puzzle and the question: What happens to the neutrinos on their way from the sun to the earth? 2. The growing evidence that our universe is filled with about 10 times more matter than is visible and the question: What is dark matter made of? 3. The supernovae explosions and the question: What do neutrinos tell us about such explosions and vice versa? The experimental investigation of these phenomena is difficult and involves unconventional techniques. These are presently under development, and bring together such seemingly disparate disciplines as astrophysics and elementary particle physics on the one hand and superconductivity and solid-state physics on the other. This book contains the proceedings of a workshop held in March 1987 at which the above subjects and their experimental investigation were discussed. The proposed experimental methods are very new. They involve frontier developments in low temperature and solid-state physics. The book should be useful to researchers and students who actively work on these subjects or plan to enter the field. It also offers the non-expert reader with some physics background a good survey of the activities in this field.
Book Synopsis Development of New Cryogenic Low-threshold Detectors for the Search of Light Dark Matter and Low-energy Neutrino Physics by : Dimitri Misiak
Download or read book Development of New Cryogenic Low-threshold Detectors for the Search of Light Dark Matter and Low-energy Neutrino Physics written by Dimitri Misiak and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Coherent Elastic Neutrino-Nucleus Scattering (CENNS) is a process predicted nearly 40 years ago. In August 2017, the COHERENT experiment reported the first keV-scale detection at the 6.7 sigma level of this process, which is a probe for the new low energy physics, opening a window on a myriad of new physics opportunities. The RICOCHET experiment aims at measuring with high accuracy the CENNS process in order to probe various exotic physics scenarios in the electroweak sector. Using cryogenic bolometers operated in a cryostat 8 meters away from the core of the ILL research nuclear reactor, the experiment will benefit from an intense neutrino flux, allowing the results of COHERENT to be reproduced in a single week. The objective of an accurate measurement will be achieved after one year of data collection, by 2024. The CRYOCUBE is a compact cubic array of cryogenic detectors with the following specifications: a very low energy threshold of O(10) eV on the thermal signal, an electromagnetic background rejection of at least 10^3 and a total target mass of 1 kg distributed among 27 germanium crystals of about 30 g each. The objective of this thesis is to propose an optimized detector design for the CRYOCUBE, inspired by the cryogenic germanium detectors equipped with charge and temperature readings of the direct dark matter search experiment EDELWEISS. This joint R&D program is based on event discrimination realized in germanium semiconductor crystals. The recoil energy of an incident particle is derived either from the increase of the crystal temperature measured by a GeNTD thermistor (heat channel) or from the excited electric charges collected by electrodes on its surface (ionization channel). This double energy measurement makes it possible to distinguish the nuclear recoils produced by the CENNS or the dark matter from the electronic radioactive background. As these recoils are of the order of O(100) eV, this thesis work is focused on the development of a new generation of cryogenic low threshold germanium detectors with particle identification. It explores how to improve the resolution in heat and ionization energy up to O(10) eV while maintaining a good rejection of background events. This study is based on the testing of prototype detectors in the IP2I cryostat, which are compared to theoretical predictions from electro-thermal and electrostatic modeling of the detectors. This manuscript begins with the definition of the CENNS process, its scientific importance and the objectives of the RICOCHET experiment. It then presents the cryogenic installation allowing the surface operation of the detectors at 20 mK in optimal conditions. An electro-thermal model of the bolometers, compared with experimental data, is developed and applied to the simulation of the noise associated with the electronics of the heat signal. The thesis then formalizes the generation of the ionization signals arising from excited charge carriers drifting in the germanium crystal under the influence of the applied electric field. The expected resolution from a future low-noise electronics is modeled based on two detector designs. They are optimized by their electrostatic simulation in a finite element calculation software. A comparison of the theoretical and experimental performance of ionization is performed on the basis of the RED80 and REDN1 prototype detectors. This work ends with the characterization of the radioactive background in the cryogenic laboratory with the analysis of the data from RED80, and in particular its neutron component, used to estimate the expected background at the ILL site for RICOCHET.

Download or read book Neutrinos and Beyond written by National Research Council and published by National Academies Press. This book was released on 2003-06-13 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The President's FY 2003 Budget Request for the National Science Foundation (NSF) under the Major Research Equipment and Facilities Construction Account called for a National Research Council (NRC) review of the scientific merits of IceCube and other proposed U.S. neutrino projects in the context of current and proposed capabilities throughout the world. The NRC committee-the Neutrino Facilities Assessment Committee (NFAC)-was charged with providing scientific assessments of two possible future science initiatives: (1) IceCube, a very large volume detector of high-energy neutrinos proposed for the South Pole and (2) a possible deep underground science facility to be developed in the United States to pursue a broad range of fundamental questions in physics and astronomy. Fourteen persons were appointed to the committee, and the first meeting was held in June 2002, with delivery of the final report expected within 6 months. The committee's assessment was to be performed in the context of current and planned neutrino capabilities throughout the world. Specifically, the study was to address the unique capabilities of each class of new experiment and any possible redundancy between the two types of facility.

Download or read book Dark Matter, Neutrinos, And Our Solar System written by Nirmala Prakash and published by World Scientific. This book was released on 2012-10-31 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dark Matter, Neutrinos, and Our Solar System is a unique enterprise that should be viewed as an important contribution to our understanding of dark matter, neutrinos and the solar system. It describes these issues in terms of links, between cosmology, particle and nuclear physics, as well as between cosmology, atmospheric and terrestrial physics. It studies the constituents of dark matter (classified as hot warm and cold) first in terms of their individual structures (baryonic and non-baryonic, massive and non-massive, interacting and non-interacting) and second, in terms of facilities available to detect these structures (large and small). Neutrinos (an important component of dark matter) are treated as a separate entity. A detailed study of these elusive (sub-atomic) particles is done, from the year 1913 when they were found as byproducts of beta decay — until the discovery in 2007 which confirmed that neutrino flavors were not more than three (as speculated by some).The last chapter of the book details the real-time stories about the “regions” that were not explored thus far, for lack of advanced technology. Their untold fascinating stories (which span up to 2010) are illustrated here datewise in full.The book concludes with the latest news that the Large Hadron Collider team at CERN has finally succeeded in producing 7 trillion electronic Volts of energy by creating head-on-collisions of protons and more protons (in search of God-particle). The energy produced was three times more than previous records.

Download or read book Searching for Dark Matter in Neutrino Beams written by Crystal Nicole Chumani Red Eagle and published by . This book was released on 2015 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dark Matter detection is currently a major area of interest for research. For the past 45 years many ideas and experiments have been investigated to explain the existence of and to detect Dark Matter. Since these experiments have yet to yield any wholly affirmative results it may be time to look for other ways to detect Dark Matter. This particular study looks at the possibilities for Dark Matter detection in neutrino beams at the Deep Underground Neutrino Experiment (DUNE). Simulations for specific parameters were run using MadGraph5 and the results for those data runs are presented and discussed. Areas of future necessary study are mentioned and ranges of possible Dark Matter masses and their effects on detection prospects are included. The initial results seem to bode well for the future of Dark Matter detection at DUNE.
