Dark Matter with Pseudoscalar-Mediated Interactions Explains the DAMA Signal and the Galactic Center Excess
TL;DR: A Dirac dark matter particle interacting with ordinary matter via the exchange of a light pseudoscalar, and it is shown that this candidate can accommodate the long-standing DAMA modulated signal and yet be compatible with all exclusion limits at 99(S)% C.L.
Enhanced Line Signals from Annihilating Kaluza-Klein Dark Matter
Chiara Arina,Chiara Arina,Torsten Bringmann,Joseph Silk,Joseph Silk,Joseph Silk,Martin Vollmann +6 more
TL;DR: In this paper, the authors calculate the contribution from those hitherto neglected resonances and show that the annihilation rate into monochromatic photons can be significantly enhanced, in a way that is much more pronounced than for the associated production of continuum photons.

TL;DR: The triplet extension of the MSSM (TMSSM) as mentioned in this paper alleviates the little hierarchy problem and provides a signicant enhancement of the loop-induced diphoton rate of the lightest CP-even Higgs h.

Dark matter versus h → γγ and h → γ Z with supersymmetric triplets
TL;DR: In this paper, the triplet extension of the MSSM (TMSSM) alleviates the little hierarchy problem and provides a significant enhancement of the loop-induced diphoton rate of the lightest CP-even Higgs h.
Co-genesis of matter and dark matter with vector-like fourth generation leptons
TL;DR: In this paper, the authors discuss aspects of a scenario for co-genesis of matter and dark matter which extends the standard model by adding a fourth generation vector-like lepton doublet and show that if the fourth neutrino is a massive pseudo-Dirac fermion with mass in the few hundred GeV range and mass splitting of about 100 keV, its lighter component can be a viable inelastic dark matter candidate.
