Renormalization Group Running of the Minimal Leptophilic Dark Matter Model toward a UV Completion
Osamu Seto, Tetsuo Shindou, Takanao Tsuyuki
We study the renormalization group running of the coupling constants in a minimal leptophilic dark matter model in which a Standard Model singlet fermion, acting as the dark matter…
Lorentzian homogeneous Ricci-flat metrics on almost abelian Lie groups
Yuichiro Sato, Takanao Tsuyuki
When the identity component of the full isometry group of a four-dimensional spacetime acts simply transitively, the unique Ricci-flat metric is the Petrov solution. This isometry…
Lower bounds on lepton flavor violating branching ratios in a radiative seesaw model
Osamu Seto, Tetsuo Shindou, Takanao Tsuyuki
We study the lepton flavor violating decays such as , , in the three-loop radiative seesaw model proposed by Krauss, Nasri, and Trodden. In this model,…
Minkowski spacetime and non-Ricci-flat compactification in heterotic supergravity
Takanao Tsuyuki
We compactify the ten-dimensional spacetime in heterotic supergravity leaving four-dimensional Minkowski spacetime. We search for nonsupersymmetric, non-Ricci-flat solutions of the…
