New Signals in Dark Matter Detectors
Author: Searching for Dark Matter with the ATLAS Detector
Author: Steven SchrammPublisher: Springer
ISBN: 3319444530
Category : Science
Languages : en
Pages : 341
Book Description
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.
The Search for Dark Matter Annihilation Signals in Neutrino Detectors

Book Description
Large-scale neutrino telescopes will be powerful toolsto observe multitude of mysterious phenomena happening in the Universe. The dark matter puzzle is listed as one of them. In this study, indirect detection of dark matter vianeutrino signals is presented. The upward muon, the contained muonand the hadronic shower fluxesare calculated, assuming annihilation/decay of the dark matter in thecore of the astrophysical objects and in the Galactic center. Direct neutrino production and secondary neutrino production from thedecay of Standard Model particles produced in the annihilation/decay of dark matter are studied. The results are contrastedto the ones previously obtained in the literature, illustrating the importance of properly treating muon propagation andenergy loss for the upward muon flux. The dependence ofthe dark matter signals on the density profile, the dark matter mass and the detector threshold are discussed. Different dark matter models (gravitino, Kaluza-Klein and leptophilic) which can account for recent observations ofsome indirect searchesare analyzed regarding their detection in the kilometer size neutrino detectors in the near future. Muon and shower rates and the minimum observation times in orderto reach 2.
Low Temperature Detectors for Neutrinos and Dark Matter

ISBN: 3642729592
Category : Technology & Engineering
Languages : en
Pages : 169
Book Description
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.
Noble Gas Detectors

Pages : 362
Book Description
This book discusses the physical properties of noble fluids, operational principles of detectors based on these media, and the best technical solutions to the design of these detectors. Essential attention is given to detector technology: purification methods and monitoring of purity, information readout methods, electronics, detection of hard ultra-violet light emission, selection of materials, cryogenics etc. The book is mostly addressed to physicists and graduate students involved in the preparation of fundamental next generation experiments, nuclear engineers developing instrumentation for national nuclear security and for monitoring nuclear materials.

Identification Of Dark Matter, The - Proceedings Of The First International Workshop

ISBN: 9814546372

Languages : en
Pages : 638
Book Description
There can be little doubt now that 90-99% of the Universe comprises dark matter. Hence it is of critical importance now not just to pursue further evidence for its existence but rather to identify what the dark matter is. Assessment of progress in this area was the objective of the first International Workshop on the Identification of Dark Matter, in particular to consider what techniques, both observational and experimental, are currently being used, how successful they are now and what new techniques will improve the prospects of identifying the likely candidates. The meeting included reviews on major particle astrophysics topics in dark matter but was largely devoted to short contributed talks on new work in the field. This book is the written proceedings of the meeting.
Dark Matter Signals

Pages : 283
Book Description
A vast number of independent astrophysical and cosmological observations suggest that the dominant form of matter in the Universe, known as dark matter, is neither luminous nor baryonic. Despite nearly half a decade of research, the non-gravitational nature of dark matter, if any, remains a mystery. Motivated primarily by preferred theoretical extensions of the Standard Model and a relatively simple production mechanism, the weakly interacting massive particle (WIMP) has long been considered to be among the most appealing dark matter particle candidates. This dissertation is comprised of largely independent works that focus on understanding and constraining various signals that could arise from WIMP dark matter. Specifically, Chapters 2 and 3 address the impact that non-standard astrophysics and particle physics could have on the observed scattering rate in direct dark matter detection experiments; Chapter 4 presents a halo-dependent and an halo-independent update on the viability of a dark matter interpretation of the CDMS-II-Si data; Chapter 5 generalizes the halo-independent analysis formalism such that the compatibility of multiple experiments can be assessed, and the preferred halo-independent parameter space can be identified, for global likelihoods comprised of at least one extended likelihood; Chapter 6 discusses the prospects for detecting gamma-rays from dark matter annihilating in local dark matter subahlos; Chapter 7 presents updated constraints on simplified dark matter models that are consistent with the Galactic Center excess; and Chapter 8 discusses the extent to which future direct detection experiments may be able to elucidate the high-energy dark matter theory from observations of low-energy nuclear recoils.
The Theory of Direct Dark Matter Detection
Author: Eugenio Del NobilePublisher: Springer Nature
ISBN: 3030952282
Category : Science
Languages : en
Pages : 261
Book Description
This book is a pedagogical guide on how to make computations in direct dark matter (DM) detection. The theory behind the calculation of direct detection cross sections and rates is presented, touching aspects related to elementary particle physics, hadronic physics, nuclear physics, and astrophysics. The book is structured in self-contained sections, covering several topics ranging from the scattering kinematics to the phenomenology of direct DM searches. It follows a model-independent approach, aiming at providing the readers with all that is needed to understand the theory and start their own analysis. Meant for graduate students and researchers with interests in particle physics and phenomenology, it is enriched with several worked examples from standard and non-standard particle DM models. Senior researchers working in different areas related to dark matter, like particle and nuclear physics, astrophysics, and cosmology, find in this book a useful and updated guide for reference.
