Dark photon and U(1)${}_{B-L}$ 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)${}_{B-L}$ gauge bosons produced via dark Higgs boson decays at the FASER and SHiP experiments. In addition to pair production of the…
