“…The bulk of our funnel region solutions corresponds to the 2mχ0 1 < m A 1 ,H 1 case, as a result of the combined constraints imposed. Interestingly, our results indicate that possible solutions exist for those regions preferred by the GeV gamma-ray excess from the Galactic Center [30,31], which is indicated 6 Indirect searches on neutrinos from some specific DM annihilation in the SUN by ICECUBE [145] and Baksan Underground Scintillator Telescope [146] are translated into model-dependent bounds on SD direct detection rate, yielding more stringent bounds on neutrino-rich annihilation modes.…”

We study the neutralino being the Lightest Supersymmetric Particle (LSP) as a cold Dark Matter (DM) candidate with a mass less than 40 GeV in the framework of the Next-to-Minimal-Supersymmetric-Standard-Model (NMSSM). We find that with the current collider constraints from LEP, the Tevatron and the LHC, there are three types of light DM solutions consistent with the direct/indirect searches as well as the relic abundance considerations: (i) A 1 , H 1 -funnels, (ii) stau coannihilation and (iii) sbottom coannihilation. Type-(i) may take place in any theory with a light scalar (or pseudo-scalar) near the LSP pair threshold; while Type-(ii) and (iii) could occur in the framework of Minimal-Supersymmetric-Standard-Model (MSSM) as well. We present a comprehensive study on the properties of these solutions and point out their immediate relevance to the experiments of the underground direct detection such as superCDMS and LUX/LZ, and the astro-physical indirect search such as Fermi-LAT. We also find that the decays of the SM-like Higgs boson may be modified appreciably and the new decay channels to the light SUSY particles may be sizable. The new light CP-even and CP-odd Higgs bosons will decay to a pair of LSPs as well as other observable final states, leading to interesting new Higgs phenomenology at colliders. For the light sfermion searches, the signals would be very challenging to observe at the LHC given the current bounds. However, a high energy and high luminosity lepton collider, such as the ILC, would be able to fully cover these scenarios by searching for events with large missing energy plus charged tracks or displaced vertices.

“…Limits from direct detection [32,33] are weaker, except in the case of DM with soft or suppressed annihilation spectra, in which case the PICO experiment [32,33] is the most constraining. Indirect DM searches by Antares [35] and Baksan [36] have set less stringent limits on the spin-dependent DM-proton scattering and are consequently not included in figure 6. Figure 7 shows new limits for all major two-body annihilation final states.…”

We present an improved event-level likelihood formalism for including neutrino telescope data in global fits to new physics. We derive limits on spin-dependent dark matter-proton scattering by employing the new formalism in a re-analysis of data from the 79-string IceCube search for dark matter annihilation in the Sun, including explicit energy information for each event. The new analysis excludes a number of models in the weak-scale minimal supersymmetric standard model (MSSM) for the first time. This work is accompanied by the public release of the 79-string IceCube data, as well as an associated computer code for applying the new likelihood to arbitrary dark matter models.

“…Thanks to the hydrogen-rich composition and large gravity of the Sun, tight limits on the spindependent (SD) scattering cross section of WIMPs on protons have been placed by neutrino telescopes such as Super-Kamiokande [8], IceCube [9], Baksan [10] and ANTARES [11]. Recent event excesses or annual modulation signals reported by direct detection experiments such as DAMA/LIBRA [12], CoGeNT [13], CRESST [14], CDMS II Si [15] and conflicting null results from other direct-and indirect-detection experiments motivate a careful search for light WIMPs below 30 GeV/c 2 .…”
