Gravitational waves as a probe of SUSY scale
Ayuki Kamada, Masaki Yamada
We investigate the sources of the Hubble-induced mass for a flat direction in supersymmetric theories and show that the sign of the Hubble-induced mass generally changes just after…
A solution to the baryon-DM coincidence problem in the CMSSM with a 126-GeV Higgs boson
Ayuki Kamada, Masahiro Kawasaki, Masaki Yamada
We show that the baryon-dark matter coincidence problem is solved in the CMSSM. The baryons and dark matter are generated simultaneously through the late-time decay of non-topologi…
Affleck-Dine Baryogenesis and Dark Matter Production after High-scale Inflation
Keisuke Harigaya, Ayuki Kamada, Masahiro Kawasaki +2
The discovery of the primordial B-mode polarisation by the BICEP2 experiment indicates inflation with a relatively high energy scale. Taking this indication into account, we propos…
Dark Matter Production in Late Time Reheating
Keisuke Harigaya, Masahiro Kawasaki, Kyohei Mukaida +1
We estimate dark matter density for the Universe with a reheating temperature smaller than the mass of dark matter, assuming dark matter to be a weakly interacting massive particle…
