Description
FASER is one of the promising experiments which search for long-lived particles beyond the Standard Model. In this talk, we focus on dark photon associating with an additional U(1) gauge symmetry, and also a scalar boson breaking this U(1) symmetry. The sensitivity to the dark photon originated from U(1) breaking scalar decays is studied. We show that a sizable number of dark photon signatures can be expected in wider parameter space than previous studies.
