“…For GeV-scale dark matter, these neutrinos would have energies well above the solar and atmospheric neutrino backgrounds at Earth-based detectors, providing a clear signal of DM annihilation. Experimental searches for these energetic neutrinos have resulted in tight bounds on DM scattering on nucleons [4][5][6], the processes that initiates the capture in the Sun. It was long thought, however, that a class of models which could not be probed by this search strategy was models in which the dark matter primarily annihilates to u, d, and s quarks.…”

Dark matter searches for monoenergetic neutrinos arising from stopped meson decay in the Sun

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.

“…Spin-dependent DM scattering is also probed by indirect searches for neutrinos produced by the annihilations of neutralinos trapped inside the Sun after scattering on protons in its interior. If the neutralinos annihilate into τ + τ − , the IceCube experiment sets the strongest such indirect limit [132], and we also show the constraint from Super-Kamiokande [160]. These constraints are currently not sensitive enough to cut into the range of the 7 We also show, for completeness, the CRESST-II [162], CDMSlite [163] and CDEX [164] constraints on σ SI p , which do not impact range of mχ0 1 found in our analysis.…”

Likelihood analysis of the sub-GUT MSSM in light of LHC 13-TeV data

et al. 2018

We describe a likelihood analysis using MasterCode of variants of the MSSM in which the soft supersymmetry-breaking parameters are assumed to have universal values at some scale M in below the supersymmetric grand unification scale M GUT , as can occur in mirage mediation and other models. In addition to M in , such 'sub-GUT' models have the 4 parameters of the CMSSM, namely a common gaugino mass m 1/2 , a common soft supersymmetrybreaking scalar mass m 0 , a common trilinear mixing parameter A and the ratio of MSSM Higgs vevs tan β, assuming that the Higgs mixing parameter μ > 0. We take into account constraints on strongly-and electroweakly-interacting sparticles from ∼ 36/fb of LHC data at 13 TeV and the LUX and 2017 PICO, XENON1T and PandaX-II searches for dark matter scattering, in addition to the previous LHC and dark matter constraints as well as full sets of flavour and electroweak constraints. We find a preference for M in ∼ 10 5 to 10 9 GeV, with M in ∼ M GUT disfavoured by χ 2 ∼ 3 due to the BR(B s,d → μ + μ − ) constraint. The lower limits on strongly-interacting sparticles are largely determined by LHC searches, and similar to those in the CMSSM. We find a preference for the LSP to be a Bino or Higgsino with mχ0 1 ∼ 1 TeV, with annihilation via heavy Higgs bosons a e-mail: j.costa15@imperial.ac.uk H/A and stop coannihilation, or chargino coannihilation, bringing the cold dark matter density into the cosmological range. We find that spin-independent dark matter scattering is likely to be within reach of the planned LUX-Zeplin and XENONnT experiments. We probe the impact of the (g − 2) μ constraint, finding similar results whether or not it is included.

“…The most compelling DM paradigm assumes that it consists of one or more particles with very weak couplings to the SM [1,2], and having the correct abundance to explain the CMB observations [3]. This hypothesis has been probed extensively using direct [4][5][6][7] and indirect detection [8][9][10][11][12][13] experiments, and in collider processes [14][15][16][17]. To date, no evidence of DM effects in any of these experiments has been confirmed.…”

A realistic model for dark matter interactions in the neutrino portal paradigm

Abstract:We discuss a simple extension of the Standard Model (SM) that provides an explicit realization of the dark-matter (DM) neutrino-portal paradigm. The dark sector is composed of a scalar Φ and a Dirac fermion Ψ, with the latter assumed to be lighter than the former. These particles interact with the SM through the exchange of a set of heavy Dirac fermion mediators that are neutral under all local SM symmetries, and also under the dark-sector symmetry that stabilizes the Ψ against decay. We show that this model can accommodate all experimental and observational constraints provided the DM mass is below ∼ 35 GeV or is in a resonant region of the Higgs or Z boson. We also show that if the dark scalar and dark fermion are almost degenerate in mass, heavier DM fermions are not excluded. We note that in this scenario DM annihilation in the cores of astrophysical objects and the galactic halo produces a monochromatic neutrino beam of energy m Ψ , which provides a clear signature for this paradigm. Other experimental signatures are also discussed.
