Very light right-handed sneutrino dark matter in the NMSSM
David G. Cerdeno, Ji-Haeng Huh, Miguel Peiro +1
Very light right-handed (RH) sneutrinos in the Next-to-Minimal Supersymmetric Standard Model can be viable candidates for cold dark matter. We investigate the prospects for their d…
Thermal leptogenesis in a supersymmetric neutrinophilic Higgs model
Naoyuki Haba, Osamu Seto
We investigate thermal leptogenesis in a supersymmetric neutrinophilic Higgs model by taking phenomenological constraints into account, where, in addition to the minimal supersymme…
Constraints from Unrealistic Vacua in the Next-to-Minimal Supersymmetric Standard Model
Yoshimi Kanehata, Tatsuo Kobayashi, Yasufumi Konishi +2
We study constraints to avoid deep unrealistic minima in the next-to-minimal supersymmetric standard model. We analyze a scalar potential along directions where all of and one of t…
Low scale thermal leptogenesis in neutrinophilic Higgs doublet models
Naoyuki Haba, Osamu Seto
It is well-known that leptogenesis in low energy scale is difficult in the conventional Type-I seesaw mechanism with hierarchical right-handed neutrino masses. We show that in a cl…
Masses of dark matter and neutrino from TeV scale spontaneous breaking
Shinya Kanemura, Osamu Seto, Takashi Shimomura
We propose a simple testable model with mass generation mechanisms for dark matter and neutrino based on the gauged symmetry and an exact parity. The $U(1)_{B-L}…
