Scalar field couplings to quadratic curvature and decay into gravitons
Yohei Ema, Kyohei Mukaida, Kazunori Nakayama
Any field, even if it lives in a completely hidden sector, interacts with the visible sector at least via the gravitational interaction. In this paper, we show that a scalar field…
Leptoflavorgenesis: baryon asymmetry of the Universe from lepton flavor violation
Kyohei Mukaida, Kai Schmitz, Masaki Yamada
Charged-lepton flavor violation (CLFV) is a smoking-gun signature of physics beyond the Standard Model. The discovery of CLFV in upcoming experiments would indicate that CLFV proce…
SU()-natural inflation
Tomohiro Fujita, Kyohei Mukaida, Kai Murai +1
We study SU() gauge fields that couple to the inflaton through the Chern-Simons term. We provide a general procedure to construct homogeneous, isotropic, and attractor solutions…
Non-Abelian Electric Field Correlator at NLO for Dark Matter Relic Abundance and Quarkonium Transport
Tobias Binder, Kyohei Mukaida, Bruno Scheihing-Hitschfeld +1
We perform a complete next-to-leading order calculation of the non-Abelian electric field correlator in a SU() plasma, which encodes properties of the plasma relevant for heav…
Axion assisted Schwinger effect
Valerie Domcke, Yohei Ema, Kyohei Mukaida
We point out an enhancement of the pair production rate of charged fermions in a strong electric field in the presence of time dependent classical axion-like background field, whic…
