Signatures of self-interacting dark matter in the matter power spectrum and the CMB / Huo, Ran ; Kaplinghat, Manoj ; Pan, Zhen ; Yu, Hai-Bo
We consider a self-interacting dark matter model in which the massive dark photon mediating the self-interaction decays to light dark fermions to avoid over-closing the universe. [...]

Loop effects on the Higgs decay widths in extended Higgs models / Kanemura, Shinya ; Kikuchi, Mariko ; Mawatari, Kentarou ; Sakurai, Kodai ; et al
In order to identify the Higgs sector using future precision data, we calculate the partial decay widths of the discovered Higgs boson with the mass of 125 GeV into fermion pairs and gauge-boson pairs with one-loop electroweak and one-loop QCD corrections in various extended Higgs models, such as the Higgs singlet model and four types of two Higgs doublet models. [...]

Testing Dark Matter models with radio telescopes in light of gravitational wave astronomy / Addazi, Andrea ; Cai, Yi-Fu ; Marcianò, Antonino
In this article we put forward a novel phenomenological paradigm in which particle physics beyond the Standard Model may be tested by radio astronomy if these are related to a first order phase transition in the early Universe. [...]
