Systematic derivation of the Boltzmann equation for electroweak baryogenesis
Motoi Endo, Yushi Mura, Tenta Tsuji
The paper derives Boltzmann equations for electroweak baryogenesis from first principles using Kadanoff–Baym equations, incorporating CP‑violating bubble‑wall gradients and self‑en…
semileptonic sum rule: exploring a sterile neutrino loophole
Motoi Endo, Syuhei Iguro, Tim Kretz +1
We investigate the semileptonic sum rule in the presence of a massive sterile neutrino. Recent measurements of charged-current semitauonic -meson decays exhibit a $\sim…
Dark Matter Interpretation of the Super-Kamiokande Antineutrino Excess in model
Motoi Endo, Yushi Mura, Tenta Tsuji
Recent Super-Kamiokande analyses of the diffuse supernova neutrino background, based on data across all SK phases, indicate a mild preference over the zero-DSNB hypothesis at the l…
Semileptonic sum rules in heavy-to-light charm decays
Motoi Endo, Syuhei Iguro, Satoshi Mishima +2
We investigate semileptonic sum rules in heavy-to-light charm decays, motivated by analogous relations in and transitions. Focusing on the $c \to d\overline{\el…
Kaon Portal to Freeze-in Dark Matter
Motoi Endo, Takumu Yamanaka
We investigate freeze-in production of light dark matter through the quark flavor-changing operator $(\bar{s}γ_μd)(\barÏγ^μÏ)$ in a low-reheating cosmology. For reheating tem…
semileptonic sum rule: orbitally excited hadrons
Motoi Endo, Syuhei Iguro, Satoshi Mishima
We study semileptonic sum rules for transitions involving orbitally excited charm hadrons. Starting from the amplitude-level relation implied by the heavy q…
