Book Synopsis Dark Matter Search with XENON1T by : Jelle Aalbers
Download or read book Dark Matter Search with XENON1T written by Jelle Aalbers and published by . This book was released on 2018 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most matter in the universe consists of 'dark matter' unknown to particle physics. Deep underground detectors such as XENON1T attempt to detect rare collisions of dark matter with ordinary atoms. This thesis describes the first dark matter search of XENON1T, how dark matter signals would appear in the detector, and the statistical techniques used in the search. The final chapters set world-leading constraints on the cross-section with which dark and normal matter interact.

Book Synopsis Study of Excess Electronic Recoil Events in XENON1T by : Evan Shockley
Download or read book Study of Excess Electronic Recoil Events in XENON1T written by Evan Shockley and published by Springer Nature. This book was released on 2021-10-30 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis summarizes the original analysis work performed by the author on data from XENON1T, a search for dark matter with a ton-size noble liquid detector operated at Gran Sasso Underground Laboratory in Italy. The nature of dark matter is one of the most open and pressing questions of modern physics, and the unique data acquired with this detector allows the exploration and investigation of several potential scenarios. The analysis of Dr. Shockley searches for a class of elusive elementary particles that interact with the electrons of ordinary atoms, instead of the nucleus. Results of the analysis present, with high confidence, an excess with respect to the expected background. Beyond more mundane explanations, this additional rate of electron-mediated interactions might be a first hint of physics beyond the standard model. This accessible thesis provides details on the detector, the data, and the theory, delivering to the reader an in-depth and coherent picture of the search for physics beyond the standard model.

Book Synopsis The XENON1T Spin-Independent WIMP Dark Matter Search Results and a Model to Characterize the Reduction of Electronegative Impurities in Its 3.2 Tonne Liquid Xenon Detector by : Zachary Greene
Download or read book The XENON1T Spin-Independent WIMP Dark Matter Search Results and a Model to Characterize the Reduction of Electronegative Impurities in Its 3.2 Tonne Liquid Xenon Detector written by Zachary Greene and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: XENON1T is the first tonne-scale TPC, and with 278.8 days of dark matter data has set the strictest limits on WIMP-nucleon interaction cross sections above WIMP masses of 6 GeV/c^2, with a minimum of 4.1 x10^{-47} cm^2 at 30 GeV/c^2. XENON1T and the analysis that led to this result are discussed, with an emphasis on electronic and nuclear recoil calibration fits, which help discriminate between background and WIMP-like events. Interactions in liquid xenon produce light and charge that are measured in TPCs. These signals are attenuated by electronegative impurities including O_2 and H_2O, which are homogeneously distributed throughout the liquid xenon. The decrease in observables enlarges the uncertainty in our analysis, and can decrease our sensitivity. Methods on measuring the charge loss are presented, and a physics model that describes the behavior of the electronegative impurity concentration over the lifetime of XENON1T is derived. The model is shown to successfully explain the more than two years of data.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An abundance of cosmological evidence suggests that cold dark matter exists and makes up 83% of the matter in the universe. At the same time, this dark matter has eluded direct detection and its identity remains a mystery. Many large international collaborations are actively searching for dark matter through its potential annihilation in high-density regions of the universe, its creation in particle accelerators, and its interaction with Standard Model particles in low-background detectors. One of the most promising dark matter candidates is the weakly interacting massive particle (WIMP) which falls naturally out of extensions of the Standard Model. A variety of detectors have been employed in the search for WIMPs, which are expected to scatter with atomic nuclei, yet none have been more successful than dual-phase liquid xenon time projection chambers (TPCs). The first ton-scale liquid xenon TPC, XENON1T, began operating in 2016 and with only 34.2 days of data has set the most strict limits on the WIMP-nucleon interaction cross sections for WIMP masses above 10 GeV/c^2, with a minimum of 7.7 × 10−47 cm^2 for 35 GeV/c^2 WIMPs.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present thesis, focus on the experimental testing of theories beyond the Standard Model, predicting a specific particle nature for the dark matter (DM) and, specifically, in the effort to directly detect leptonically interacting DM particles with the use of the low-background, underground detector XENON1T. We, initially, investigate the electronic recoil (ER) background in the search of a possible modulation, which is expected due to the relative motion between the Earth and the DM halo. In the absence of observation of WIMP-induced nuclear recoils, an alternative interpretation through a leptophilic DM, finds its place as a natural hypothesis that should be tested, taking advantage of the long-term stability of the ER background of the XENON1T detector. Then, we focus on the search of leptonically interacting DM particles with mass in the sub-GeV scale, emerging in the framework of so-called,”hidden sector" theories, predicting a leptophilic DM with mass in MeV scale, that could interact with the target causing inelastic atomic processes, such as ionization. It is in the region of this expected signal that a huge and, so far, incomprehensible background arises, driven by the so-called single electrons, small charge signals that appear to derive from a multitude of quantum processes in the atomic level of LXe. What can we infer about leptophilic DM without the possibility of background subtraction? Can we classify the processes that create this background? How can machine learning techniques, like Neural Networks, mitigate such backgrounds? These are some of the questions, about the exciting topic of DM direct detection, that we will try to address in this work.

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.
