The mass-coupling effect in leptogenesis
Shinya Kanemura, Shao-Ping Li
Particle decay in leptogenesis provides a simple avenue to explain the baryon asymmetric universe, where the decaying particle can provide the out-of-equilibrium condition to creat…

Bounds and detection of MeV-scale dark matter annihilation to neutrinos
Shinya Kanemura, Shao-Ping Li, Dibyendu Nanda
Current and most upcoming neutrino detectors can only reach a dark matter annihilation cross section to neutrinos larger than the standard freeze-out value, but they open intriguin…

Forbidden neutrinogenesis
Shinya Kanemura, Shao-Ping Li
The origin of neutrino masses can be simply attributed to a new scalar beyond the Standard Model. We demonstrate that leptogenesis can explain the baryon asymmetry of the universe…
