Discovery potential of a long-lived partner of inelastic dark matter at MATHUSLA in $U (1)_{X_{3}}$ extension of the standard model

Nobuchika Okada, Osamu Seto

We investigate the discovery potential at the MATHUSLA experiment of a long-lived particle (LLP), which is the heavier state of inelastic scalar dark matter (DM) in third generatio…

Stable dark matter from Pauli blocking in the degenerate fermion background with Quantum Field Theory

Wonsub Cho, Ki-Young Choi, Junghoon Joh +1

We study a mechanism to make dark matter stable based on the Pauli blocking in the fermion background. In the background where fermions occupy the states, the decay of dark matter…

Freeze-in sterile neutrino dark matter in a feebly gauged $B - L$ model

Osamu Seto, Takashi Shimomura, Yoshiki Uchida

We consider the gauged $U (1)_{B - L}$ model and examine the situation where the sterile neutrino is a dark matter candidate produced by the freeze-in mechanism. In our model, the dar…
