“…Results are shown in Fig. 13 for spin-independent (D5) and spin-dependent (D8, D9) χ-nucleon interactions and are compared to measurements from various DM search experiments [73][74][75][76][77][78][79][80][81][82][83][84][85]. The search for dark-matter pair production in association with a γ at the LHC extends the limits on the χ-nucleon scattering cross section into the low-mass region m χ < 10 GeV where the astroparticle experiments have less sensitivity due to the very low-energy recoils such low-mass DM particles would induce.…”

Results of a search for new phenomena in events with an energetic photon and large missing transverse momentum with the ATLAS experiment at the LHC are reported. Data were collected in proton-proton collisions at a center-of-mass energy of 8 TeV and correspond to an integrated luminosity of 20.3 fb −1 . The observed data are well described by the expected Standard Model backgrounds. The expected (observed) upper limit on the fiducial cross section for the production of events with a photon and large missing transverse momentum is 6.1 (5.3) fb at 95% confidence level. Exclusion limits are presented on models of new phenomena with large extra spatial dimensions, supersymmetric quarks, and direct pair production of dark-matter candidates.

“…In figure 2 we plot the 90% CL sensitivities for dark matter annihilation into light quarks in the stopped π + /K + decay channels of KamLAND, DUNE, Super-Kamiokande and Hyper-Kamiokande, as well as the 90% CL limits of PICASSO [47] and PICO-2L [48]. Note, we do not plot the sensitivity of KamLAND, Super-Kamiokande or Hyper-Kamiokande to monoenergetic 30 MeV neutrinos, since for these targets the energy of the produced electron is relatively small compared to that of the incoming neutrino, making the backgrounds harder to estimate.…”

“…We assume = 10%, a normal hierarchy, and that dark matter in the Sun annihilates only to first generation quarks. Also plotted are the 90% CL bounds from PICASSO [47] and PICO-2L [48] (dashed grey and black, respectively). The shaded area represents the region where interactions with the thermal bath of nucleons in the Sun cause dark matter particles to easily be ejected (or evaporate) from the Sun [25,26].…”

Dark matter can be gravitationally captured by the Sun after scattering off solar nuclei. Annihilations of the dark matter trapped and accumulated in the centre of the Sun could result in one of the most detectable and recognizable signals for dark matter. Searches for high-energy neutrinos produced in the decay of annihilation products have yielded extremely competitive constraints on the spin-dependent scattering cross sections of dark matter with nuclei. Recently, the low energy neutrino signal arising from dark-matter annihilation to quarks which then hadronize and shower has been suggested as a competitive and complementary search strategy. These high-multiplicity hadronic showers give rise to a large amount of pions which will come to rest in the Sun and decay, leading to a unique sub-GeV neutrino signal. We here improve on previous works by considering the monoenergetic neutrino signal arising from both pion and kaon decay. We consider searches at liquid scintillation, liquid argon, and water Cherenkov detectors and find very competitive sensitivities for few-GeV dark matter masses.

“…Bounds on the σ SD from direct detection experiments such as PICASSO [57], COUPP [58], SIMPLE [59], KIMS [60] IceCube [61], XENON100 [62] (see also [63]) and the Baksan Neutrino Observatory [64] are not much constraining yet for light neutralino DM. Nevertheless, LHC searches for events with a monojet plus missing transverse momentum [65,66] can be translated into bounds on neutralino-nucleon scattering crosssections [67,68,69,70].…”

We investigate the current status of the light neutralino dark matter scenario within the minimal supersymmetric standard model (MSSM) taking into account latest results from the LHC. A discussion of the relevant constraints, in particular from the dark matter relic abundance, leads us to a manageable simplified model defined by a subset of MSSM parameters. Within this simplified model we reinterpret a recent search for electroweak supersymmetric particle production based on a signature including multi-taus plus missing transverse momentum performed by the ATLAS collaboration. In this way we derive stringent constraints on the light neutralino parameter space. In combination with further experimental information from the LHC, such as dark matter searches in the monojet channel and constraints on invisible Higgs decays, we obtain a lower bound on the lightest neutralino mass of about 24 GeV. This limit is stronger than any current limit set by underground direct dark matter searches or indirect detection experiments. With a mild improvement of the sensitivity of the multi-tau search, light neutralino dark matter can be fully tested up to about 30 GeV.
