Book excerpt: Several new-physics (NP) models predict the existence of low-mass Higgs states and light dark matter candidates. Previous BABAR searches have given null results for these new states and have excluded large regions of the NP models parameter space. We report on new searches on light Higgs and light dark matter at BABAR using the 516 fb-1 of data collected with the BABAR detector at the PEP-II asymmetric-energy e+e- collider at the SLAC National Accelerator Laboratory.

Download or read book Discovering Dark Matter written by Philip Wolny and published by The Rosen Publishing Group, Inc. This book was released on 2014-12-15 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discoveries in physics that inform current dark matter theory, everything from Newtonian gravity to Einstein's relativity to the Higgs boson, are examined in this authoritative guide. It examines the biggest question facing physicists today: if we are only seeing about four percent of matter in the universe, what is the rest of it made of? The lengths that scientists are going to find what they call dark matter are revealed. Alternative theories to dark matter are also discussed, as are the scientists who don't believe that dark matter exists and are conducting their own experiments to disprove its existence.

This book was released on 2015 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area of dark matter is one of the most interesting and exciting topics in physics today. Existing at the intersection of particle physics and astrophysics, the existence of a new dark matter particle can be used to explain many astrophysical and cosmological observations, as well as to reconcile outstanding issues in the standard model of particle physics. Experiments such as SuperCDMS are built to detect dark matter in the lab by looking for low-energy nuclear recoils produced by collisions between dark matter particles and atoms in terrestrial detectors. SuperCDMS Soudan is particularly well-suited to follow up on possible hints of low-mass dark matter seen by other recent experiments because of its low thresholds and excellent background discrimination. Analyzing SuperCDMS Soudan data to look for low-mass dark matter comes with particular challenges because of the low signal-to-noise very near threshold. However, with a detailed background model developed by scaling high-energy events down into the low-energy signal region, SuperCDMS Soudan produced worldleading limits on the existence of low-mass dark matter. In addition, a few SuperCDMS Soudan detectors experienced cold hardware problems that can affect the data collected. Of particular interest is one detector considered for the low-mass WIMP search that has one of its charge electrodes shorted to chassis ground. Three events were observed in this detector upon unblinding the SuperCDMS Soudan low-energy data, even though

This book was released on 2013-11-25 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings provide the latest results on dark matter and dark energy research. The UCLA Department of Physics and Astronomy hosted its tenth Dark Matter and Dark Energy conference in Marina del Rey and brought together all the leaders in the field. The symposium provided a scientific forum for the latest discussions in the field. Topics covered at the symposium: •Status of measurements of the equation of state of dark energy and new experiments •The search for missing energy events at the LHC and implications for dark matter search •Theoretical calculations on all forms of dark matter (SUSY, axions, sterile neutrinos, etc.) •Status of the indirect search for dark matter •Status of the direct search for dark matter in detectors around the world •The low-mass wimp search region •The next generation of very large dark matter detectors •New underground laboratories for dark matter search

Available in PDF, EPUB and Kindle. Book excerpt: "It is hypothesized that 26% of the mass and energy content of the universe consists of Dark Matter. The most promising Dark Matter candidates are Weakly Interacting Massive Particles (WIMP). If WIMPs are the Dark Matter particles, then they could be directly de-tected via their scattering off nuclei. The XENON100 experiment aims to detect the scattering of a WIMP with a xenon nucleus. This experiment is a xenon-based dual-phase (liquid-gas) Time Projection Chamber (TPC). The interaction of a particle in the TPC produces both scintillation photons and ionization electrons, which are both detected as light signals by photomultipliers. So far, the XENON100 experiment has not observed WIMPs, and exclusion limits have been produced. The data analysis relies on an accurate description of the backgrounds. In this thesis I present an analysis that assumes potentially unknown backgrounds to be present in the data. In this way, a WIMP exclusion limit without background subtraction is calculated with a minimum WIMP-nucleon cross section of 2.05 × 10-45 cm2 at a WIMP mass of 50 GeV. Furthermore, I developed a new method to enhance the sensitivity of the XENON100 experiment towards low-mass WIMPs using solely the ionization signal to calculate the recoil energy. Using this method, the sensitivity of the XENON100 experiment is improved by several orders of magnitude for WIMP masses below 7 GeV, excluding a WIMP-nucleon cross section of 1.4 × 10-41 cm2 at a WIMP mass of 6 GeV."--Samenvatting auteur.

This book was released on 2020-08-13 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: This primer describes the general model independent searches for new physics phenomena beyond the Standard Model of particle physics. First, the motivation for performing general model independent experimental searches for new physics is presented by giving an overview of the current theoretical understanding of particle physics in terms of the Standard Model of particle physics and its shortcomings. Then, the concept and features of general model independent search for new physics at collider based experiments is explained. This is followed by an overview of such searches performed in past high energy physics experiments and the current status of such searches, particularly in the context of the experiments at the LHC. Finally, the future prospects of such general model independent searches, with possible improvements using new tools such as machine learning techniques, is discussed.
