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