Inflationary cosmology and the standard model Higgs with a small Hubble induced mass
Kohei Kamada
We study the dynamics of the standard model Higgs field in the inflationary cosmology. Since metastability of our vacuum is indicated by the current experimental data of the Higgs…
Effects of cosmic strings with delayed scaling on CMB anisotropy
Kohei Kamada, Yuhei Miyamoto, Daisuke Yamauchi +1
The network of cosmic strings generated in a phase transition during inflation enters the scaling regime later than that of usual strings. If it occurs after the recombination, tem…
Topological inflation from the Starobinsky model in supergravity
Kohei Kamada, Jun'ichi Yokoyama
We consider the ghost-free higher order corrections to the Starobinsky model in the old minimal supergravity. In general, higher order corrections cannot be forbidden by symmetries…
Hybrid Inflation in the Complex Plane
Wilfried Buchmuller, Valerie Domcke, Kohei Kamada +1
Supersymmetric hybrid inflation is an exquisite framework to connect inflationary cosmology to particle physics at the scale of grand unification. Ending in a phase transition asso…
