Leptogenesis via Axion Oscillations after Inflation
Alexander Kusenko, Kai Schmitz, Tsutomu T. Yanagida
Once a light axionlike scalar field couples to the electroweak gauge bosons, its classical motion during reheating induces an effective chemical potential for the fermion number. I…
Dynamical D-Terms in Supergravity
Valerie Domcke, Kai Schmitz, Tsutomu T. Yanagida
Most phenomenological models of supersymmetry breaking rely on nonzero F-terms rather than nonzero D-terms. An important reason why D-terms are often neglected is that it turns out…
Dynamical Fractional Chaotic Inflation -- Dynamical Generation of a Fractional Power-Law Potential for Chaotic Inflation
Keisuke Harigaya, Masahiro Ibe, Kai Schmitz +1
Chaotic inflation based on a simple monomial scalar potential, V(phi) ~ phi^p, is an attractive large-field model of inflation capable of generating a sizable tensor-to-scalar rati…
The Chaotic Regime of D-Term Inflation
W. Buchmuller, V. Domcke, K. Schmitz
We consider D-term inflation for small couplings of the inflaton to matter fields. Standard hybrid inflation then ends at a critical value of the inflaton field that exceeds the Pl…
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…
Dynamical Chaotic Inflation in the Light of BICEP2
Keisuke Harigaya, Masahiro Ibe, Kai Schmitz +1
The measurement of a large tensor-to-scalar ratio by the BICEP2 experiment, r = 0.20 (-0.05)(+0.07), severely restricts the landscape of viable inflationary models and shifts atten…
