Classification of minimal models producing b, c and tau masses at one-loop level
Lucia Stockdale, Raymond R. Volkas
The Standard Model neither provides a dynamical explanation for the quark and lepton mass hierarchies, nor a rationale for why all of these masses save that of the top quark are su…
Higgs Yukawa coupling constraints on a benchmark one-loop radiative mass model for the bottom, charm and tau
Lucia Stockdale, Raymond R. Volkas
Measurements of Higgs boson Yukawa couplings to Standard Model (SM) fermions constrain radiative mass models for those species. Such models, motivated by the observed fermion mass…
Muonphilic asymmetric dark matter at a future muon collider
Arnab Roy, Raymond R. Volkas
We explore phenomenological constraints on, and future muon collider sensitivities to, the parameter spaces of various muonphilic portals to fermionic asymmetric dark matter (ADM).…
Dark Matter Freeze-in from a Reheaton
Avirup Ghosh, Alexei H. Sopov, Raymond R. Volkas
We consider the Standard Model (SM) extended by a secluded gauge sector encompassing a Dirac fermion () dark matter (DM), an abelian gauge boson and a SM-si…
A new idea for relating the asymmetric dark matter mass scale to the proton mass
Peter Cox, Rafael E. Pérez, Raymond R. Volkas
Asymmetric dark matter is a well-motivated approach to explain the apparent coincidence between the relic densities of visible and dark matter, . A complete ex…
The post-inflationary cosmology of the VISH axion-majoron model
Alexei H. Sopov, Carlos Tamarit, Raymond R. Volkas
It was previously shown how several explanatory deficiencies of the Standard Model (including the origin of dark matter, matter-antimatter asymmetry, small active neutrino mass, st…
