Renormalization-Scale Uncertainty in the Decay Rate of False Vacuum
Motoi Endo, Takeo Moroi, Mihoko M. Nojiri +1
We study radiative corrections to the decay rate of false vacua, paying particular attention to the renormalization-scale dependence of the decay rate. The decay rate exponentially…
Revisiting Big-Bang Nucleosynthesis Constraints on Dark-Matter Annihilation
Masahiro Kawasaki, Kazunori Kohri, Takeo Moroi +1
We study the effects of dark-matter annihilation during the epoch of big-bang nucleosynthesis on the primordial abundances of light elements. We improve the calculation of the ligh…
Beam Dump Experiment at Future Electron-Positron Colliders
Shinya Kanemura, Takeo Moroi, Tomohiko Tanabe
We propose a new beam dump experiment at future colliders with electron () and positron () beams, BDee, which will provide a new possibility to search for hidden particle…
AMS-02 Antiprotons from Annihilating or Decaying Dark Matter
Koichi Hamaguchi, Takeo Moroi, Kazunori Nakayama
Recently the AMS-02 experiment reported an excess of cosmic ray antiprotons over the expected astrophysical background. We interpret the excess as a signal from annihilating or dec…
Footprints of Supersymmetry on Higgs Decay
Motoi Endo, Takeo Moroi, Mihoko M. Nojiri
Motivated by future collider proposals that aim to measure the Higgs properties precisely, we study the partial decay widths of the lightest Higgs boson in the minimal supersymmetr…
