“…However, these limits conflict with earlier CDMS-II [18], DAMA/LIBRA [19,20,21,22,23], and CoGeNT [24,25,26,27,28] results, which are consistent with light (≈ 10 GeV) dark matter. The results of CDMS-II and CoGeNT can be made compatible with the limits of LUX [15], CDMSlite [18] and XENON [29] if dark matter is not isospin-invariant [30,31,32]. In any case, the high backgrounds and low signal amplitudes of direct detection experiments make analysis, particularly at low WIMP mass, challenging, and direct experiments optimized for low-energy recoils, such as PICO [33], are still orders of magnitude less sensitive for the spin-independent case than LUX or CDMS.…”

Review of the theoretical and experimental status of dark matter identification with cosmic-ray antideuterons

See paper for full list of authors - 67 pages, 20 figures; submitted to Physics ReportsInternational audienceRecent years have seen increased theoretical and experimental effort towards the first-ever detection of cosmic-ray antideuterons, in particular as an indirect signature of dark matter annihilation or decay. In contrast to indirect dark matter searches using positrons, antiprotons, or gamma-rays, which suffer from relatively high and uncertain astrophysical backgrounds, searches with antideuterons benefit from very suppressed conventional backgrounds, offering a potential breakthrough in unexplored phase space for dark matter. This article is based on the first dedicated cosmic-ray antideuteron workshop, which was held at UCLA in June 2014. It reviews broad classes of dark matter candidates that result in detectable cosmic-ray antideuteron fluxes, as well as the status and prospects of current experimental searches. The coalescence model of antideuteron production and the influence of antideuteron measurements at particle colliders are discussed. This is followed by a review of the modeling of antideuteron propagation through the magnetic fields, plasma currents, and molecular material of our Galaxy, the solar system, the Earth's geomagnetic field, and the atmosphere. Finally, the three ongoing or planned experiments that are sensitive to cosmic-ray antideuterons, BESS, AMS-02, and GAPS, are detailed. As cosmic-ray antideuteron detection is a rare event search, multiple experiments with orthogonal techniques and backgrounds are essential. Many theoretical and experimental groups have contributed to these studies over the last decade, this review aims to provide the first coherent discussion of the relevant dark matter theories that antideuterons probe, the challenges to predictions and interpretations of antideuteron signals, and the experimental efforts toward cosmic antideuteron detection

“…There are many reasons why such a light dark matter search is interesting. First, recent data [114][115][116][117] from the direct WIMP (weakly interacting massive particle) searches suggest possible signals of dark matter particles in the lighter mass region. For example, SuperCDMS is also aiming the low mass dark matter search by utilizing the ionization signals [118].…”

Beyond Standard Model Searches in the MiniBooNE Experiment

The MiniBooNE Experiment has contributed substantially to beyond standard model searches in the neutrino sector. The experiment was originally designed to test the ∆m 2 ∼ 1 eV 2 region of the sterile neutrino hypothesis by observing ν e (ν e ) charged current quasi-elastic signals from a ν µ (ν µ ) beam. MiniBooNE observed excesses of ν e andν e -candidate events in neutrino and anti-neutrino mode, respectively. To date, these excesses have not been explained within the neutrino Standard Model (νSM), the Standard Model extended for three massive neutrinos. Confirmation is required by future experiments such as MicroBooNE. MiniBooNE also provided an opportunity for precision studies of Lorentz violation. The results set strict limits for the first time on several parameters of the Standard Model-Extension, the generic formalism for considering Lorentz violation. Most recently, an extension to MiniBooNE running, with a beam tuned in beam-dump mode, is being performed to search for dark sector particles. This review describes these studies, demonstrating that short baseline neutrino experiments are rich environments in new physics searches. 1 arXiv:1404.7759v1 [hep-ex] 30 Apr 2014Across the particle physics community, the mysterious periodic-table-like nature of the Standard Model (SM) is motivating searches for new particles, new forces and new properties of the particles that are known. The neutrino sector is proving a rich environment for these searches. Having already found one beyond-Standard-Model (BSM) effect-neutrino mass [1]-a series of experiments are pursuing other potential signals. Unlike the case of three-neutrino oscillation measurements within νSM, many of these searches are pursued over short baselines, from a few meters to approximately a kilometer. The Mini Booster Neutrino Experiment (MiniBooNE) at Fermi National Accelerator Laboratory (Fermilab) is an excellent example, having contributed substantially to BSM studies.This review describes the MiniBooNE BSM program. We begin by describing the experiment. This is followed by a discussion of the MiniBooNE cross section studies, which have been essential input to both the BSM searches within this experiment, and also to other experiments, including T2K most recently [2]. We then describe three searches: the sterile neutrino search which motivated the experiment, Lorentz violation searches which set the first limits on five neutrino sector parameters, and the search for dark sector particles which is now being pursued with a re-configured beam. MiniBooNE (running from 2002MiniBooNE (running from -2012 was originally designed to test the LSND signal [3]. In the LSND experiment, low energy (0 to 53 MeV) muon anti-neutrinos were produced by pion decayat-rest (DAR), and were detected by the liquid-scintillator-based LSND detector at 31 m from the target. The observed 3.8σ excess ofν e candidate events could be interpreted as oscillations in the ∆m 2 ∼ 1 eV 2 region within a simple two massive neutrino oscillation hypothesis, where the oscillation proba...

We construct a model based on an extra gauge symmetry, SU(2) X ×U(1) B−L , which can provide gauge bosons to serve as weakly-interacting massive particle dark matter. The stability of the dark matter is naturally guaranteed by a discrete Z 2 symmetry that is a subgroup of SU(2) X . The dark matter interacts with standard model fermions by exchanging gauge bosons which are linear combinations of SU(2) X ×U(1) B−L gauge bosons. With the appropriate choice of representation for the new scalar multiplet whose vacuum expectation value spontaneously breaks the SU(2) X symmetry, the relation between the new gauge boson masses can naturally lead to resonant pair annihilation of the dark matter. After exploring the parameter space of the new gauge couplings subject to constraints from collider data and the observed relic density, we use the results to evaluate the cross section of the dark matter scattering off nucleons and compare it with data from the latest direct detection experiments. We find allowed parameter regions that can be probed by future direct searches for dark matter and LHC searches for new particles.
