Dark photon and U(1) gauge boson from dark Higgs boson decays at FASER and SHiP
Takeshi Araki, Kento Asai, Yohei Nakashima +3
We study the sensitivity to dark photons and U(1) gauge bosons produced via dark Higgs boson decays at the FASER and SHiP experiments. In addition to pair production of the…
Systematic study of lepton-flavor-violating dark matter interactions via indirect detection in effective field theories
Sahabub Jahedi, Jin-Han Liang, Yi Liao +2
Lepton-flavor-violating (LFV) interactions involving dark matter (DM) particles remain a largely unexplored area. In this study, we systematically investigate LFV DM interactions w…
Composite Asymmetric Dark Matter from Primordial Black Holes
Takumi Kuwahara, Yoshiki Uchida
We investigate a cogenesis scenario for composite asymmetric dark matter framework: a dark sector has a similar strong dynamics to quantum chromodynamics in the standard model, and…
Effective field theory for type II seesaw model --symmetric phase v.s. broken phase--
Yi Liao, Xiao-Dong Ma, Yoshiki Uchida
Effective field theory is an effective approach to parameterizing effects of high energy scale physics in low energy measurements. The two popular frameworks for physics beyond the…
