This book was released on 2013 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: PICASSO (Project in Canada to Search for Supersymmetric Objects) is a direct dark matter search experiment located at SNOLAB. PICASSO uses su- perheated Freon-10 (C4 F10) as target for elastic scattering of Weakly Interact- ing Massive Particles (WIMPs) which are the most favored particle candidates for dark matter. In this thesis, a "geyser", a small-scale working prototype of a low dead-time dark matter detector, is described. This detector has a novel design for the recovery of the active fluid. It is demonstrated that the detector can stably sustain superheated fluid for more than 48 hours. Systematic studies have been performed of the stability, the dead time, energy thresholds and the operational parameters of the geyser. The geyser was operated stably for more than 73 hours, out of which 40 hours of thermodynamic, optical and acoustic data were analysed. An image analysis algorithm was developed to localize events. Acoustic data was analyzed using techniques from the PICASSO experiment. A strong discrimination effect between alpha-like events and nuclear recoil-like events was found.

Available in PDF, EPUB and Kindle. Book excerpt: The PICASSO and COUPP collaborations use superheated liquid detectors to search for cold dark matter through the direct detection of weakly interacting massive particles (WIMPs). These experiments, located in the underground laboratory of SNOLAB, Canada, detect phase transitions triggered by nuclear recoils in the keV range induced by interactions with WIMPs. We present details of the construction and operation of these detectors as well as the results, obtained by several years of observations. We also introduce PICO, which is a joint effort of the two collaborations to build a second generation ton-scale bubble chamber with 250 liters of active liquid.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Dark matter detection remains one of the main unresolved problems in physics. Accounting for almost 85% of all the matter density in the Universe, it was inferred through many astronomical observations, but no dark matter particle has been detected yet. The PICO experiment has this objective as its purpose, using the bubble chamber in order to do so. PICO can detect extremely low-energy interactions in its superheated liquid detectors, located in the SNOLAB underground laboratory in Sudbury, Ontario. PICO has and has had multiple dark matter search detectors, as well as small detectors used to perform calibrations and tests. PICO-0.1 is a calibration chamber located at the University of Montreal and was used for the studies presented in this thesis. In this thesis, data and analysis of measurements made with PICO-0.1 are presented. A study of the Seitz threshold - theoretical energy threshold for an event to occur in a bubble chamber - is made, with the monoenergetic reaction 35Cl(nth,p)35S in C2ClF5; the study of the monoenergetic 35S recoil, directly inside the detector, is presented. Furthermore, the detection of proton recoils in PICO-0.1 is detailed; first through the analysis of the acoustic signal of the proton produced by 35Cl(nth,p)35S, and second through elastic scattering of neutrons and high energy gamma rays on hydrogen in C2H2F4.

Download or read book Search for Dark Matter with the ATLAS Detector written by Johanna Gramling and published by Springer. This book was released on 2018-08-01 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses searches for Dark Matter at the CERN’s LHC, the world’s most powerful accelerator. It introduces the relevant theoretical framework and includes an in-depth discussion of the Effective Field Theory approach to Dark Matter production and its validity, as well as an overview of the formalism of Simplified Dark Matter models. Despite overwhelming astrophysical evidence for Dark Matter and numerous experimental efforts to detect it, the nature of Dark Matter still remains a mystery and has become one of the hottest research topics in fundamental physics. Two searches for Dark Matter are presented, performed on data collected with the ATLAS experiment. They analyze missing-energy final states with a jet or with top quarks. The analyses are explained in detail, and the outcomes and their interpretations are discussed, also in view of the precedent analysis of theoretical approaches. Given its depth of coverage, the book represents an excellent reference guide for all physicists interested in understanding the theoretical and experimental considerations relevant to Dark Matter searches at the LHC.

Available in PDF, EPUB and Kindle. Book excerpt: This book brings together reviews from leading international authorities on the developments in the study of dark matter and dark energy, as seen from both their cosmological and particle physics side. Studying the physical and astrophysical properties of the dark components of our Universe is a crucial step towards the ultimate goal of unveiling their nature. The work developed from a doctoral school sponsored by the Italian Society of General Relativity and Gravitation. The book starts with a concise introduction to the standard cosmological model, as well as with a presentation of the theory of linear perturbations around a homogeneous and isotropic background. It covers the particle physics and cosmological aspects of dark matter and (dynamical) dark energy, including a discussion of how modified theories of gravity could provide a possible candidate for dark energy. A detailed presentation is also given of the possible ways of testing the theory in terms of cosmic microwave background, galaxy redshift surveys and weak gravitational lensing observations. Included is a chapter reviewing extensively the direct and indirect methods of detection of the hypothetical dark matter particles. Also included is a self-contained introduction to the techniques and most important results of numerical (e.g. N-body) simulations in cosmology. " This volume will be useful to researchers, PhD and graduate students in Astrophysics, Cosmology Physics and Mathematics, who are interested in cosmology, dark matter and dark energy.

Download or read book Direct Search for Dark Matter by Using Dual-phase Liquid Xenon Detector and Measurement of Nuclear Recoils in Liquid Argon written by Yixiong Meng and published by . This book was released on 2015 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cosmological and Astrophysical observations provide compelling evidences for the existence of dark matter in the universe. One class of dark matter candidates, the Weakly Interacting Massive Particles (WIMPs), has been predicted in many particle physics theories. Direct detection experiments using dual- phase liquid noble element detectors report the best sensitivities to the detection of the dark matter particles. The next generation direct detection experiments using the same technology, are actively been built and expected to give a factor of 100 improvement on the current best sensitivity. This thesis discusses the measurement of nuclear recoils in a dual-phase liquid argon detector using a bunched neutron beam generated by linear accelerator facility at accelerator laboratory in Notre Dame University. Nuclear recoils of en- ergy ranging from 10.8 keVnr to 49.9 keVnr are measured under different drift field configurations. An electric field quenching on nuclear recoils in liquid argon is dis- covered and quantified for the first time. This quenching effect is also found to be drift field and recoil energy dependent. By varying the drift field amplitude from 100 V/cm to 1000 V/cm for each nuclear recoil energy, the quenching effect are measured as a function of nuclear recoil energy and drift field amplitude. Results from this measurement is used in the direct dark matter detection experiment to calculate the final sensitivity of direct dark matter search. A separate work on the optimization of detector design for the XENON1T detector is also discussed in detail. Finite element simulation tool is used to design and optimize the electric field in XENON1T time projection chamber. As part of the design of XENON1T detector, electron transparency across metal grids of different geometrical configurations are also studied.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the search for Dark Matter at the LHC in the mono-jet plus missing transverse momentum final state, using the full dataset recorded in 2012 by the ATLAS Experiment. It is the first time that the number of jets is not explicitly restricted to one or two, thus increasing the sensitivity to new signals. Instead, a balance between the most energetic jet and the missing transverse momentum is required, thus selecting mono-jet-like final states. Collider searches for Dark Matter have typically used signal models employing effective field theories (EFTs), even when comparing to results from direct and indirect detection experiments, where the difference in energy scale renders many such comparisons invalid. The thesis features the first robust and comprehensive treatment of the validity of EFTs in collider searches, and provides a means by which the different classifications of Dark Matter experiments can be compared on a sound and fair basis.
