  1. 184. Where is a Miracle-less WIMP Ruled out?
    Jason Arakawa
    20/05/2021, 14:00

    We examine a real electroweak triplet scalar field as dark matter, abandoning the requirement that its relic abundance is determined through freeze out in a standard cosmological history (a situation which we refer to as `miracle-less WIMP'). We extract the bounds on such a particle from collider searches, searches for direct scattering with terrestrial targets, and searches for the indirect...

  2. 252. Constraints on CP-Violating Higgs Portal Majorana Dark Matter

    Dark Matter

    We discuss the viability of higgs portal majorana dark matter in light of current constraints, considering parameter ranges motivated by the thermal relic abundance and the potential GCE annihilation signal. Typically in these models, the mass of the dark matter is tuned so that annihilation occurs through the higgs resonance, in order to get a large enough annihilation signal while avoiding...

  3. 265. Phenomenology of Dark matter in two higgs doublet model with complex scalar singlet

    Dark Matter

    Extensions of the two higgs doublet models with a singlet scalar can easily accommodate all current experimental constraints and are highly motivated candidates for Beyond Standard Model Physics. It can successfully provide a dark matter candidate, explain baryogenesis and provide gravitational wave signals. In this work, we focus on the dark matter phenomenology of the two higgs doublet model...

  4. 87. Scalar Multiplet Dark Matter in a Fast Expanding Universe: resurrection of the desert region

    Dark Matter

    We examine the impact of a faster expanding Universe on the phenomenology of scalar dark matter (DM) associated with SU(2)L multiplets. Earlier works with radiation dominated Universe have reported the presence of desert region for both inert SU(2)L doublet and triplet DM candidates where the DM is under abundant. We find that the existence of a faster expanding component before BBN can revive...

  5. 183. Twin Higgs Portal Dark Matter
    Shayne Gryba (University of Toronto)

    Dark Matter

    Many minimal models of dark matter (DM) or canonical solutions to the hierarchy problem are either excluded or severely constrained by LHC and direct detection null results. In particular, Higgs Portal Dark Matter (HPDM) features a singlet scalar minimally coupled to the Higgs, and because the same coupling mediates both thermal freeze out and direct detection the measured dark matter relic...

  6. 194. Constraints on dark matter-nucleon effective couplings in the presence of kinematically distinct halo substructures using the DEAP-3600 detector

    Dark Matter

    DEAP-3600 is a WIMP dark matter direct-detection experiment located deep underground at the SNOLAB facility (Sudbury, Canada) which uses liquid argon as the target material. During the first year of search, zero candidate events were observed, resulting in limits on the isoscalar, spin-independent WIMP-nucleon cross-section above 3.9 x 10-45 cm2 (1.5x10-44 cm2) for 100 GeV/c2 (1 TeV/c2) WIMP...
