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…

Dark photon pair production via off-shell dark Higgs at FASER

Takeshi Araki, Kento Asai, Yohei Nakashima +1

We consider a dark photon model in which the dark U(1) gauge symmetry is spontaneously broken by a vacuum expectation value of a new scalar boson. We focus on the ForwArd Search Ex…

New Constraint on Dark Photon at T2K Off-Axis Near Detector

Takeshi Araki, Kento Asai, Tomoya Iizawa +3

The T2K experiment is one of the most powerful long-baseline experiments to investigate neutrino oscillations. The off-axis near detector called ND280 is installed 280 m downstream…

Search for Lepton Flavor Violating Decay at FASER

Takeshi Araki, Kento Asai, Hidetoshi Otono +2

FASER is one of the promising experiments which search for long-lived particles beyond the Standard Model. In this paper, we consider charged lepton flavor violation (CLFV) via a l…

The Forward Physics Facility at the High-Luminosity LHC

Jonathan L. Feng, Felix Kling, Mary Hall Reno +233

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing L…

Electron Beam Dump Constraints on Light Bosons with Lepton Flavor Violating Couplings

Takeshi Araki, Kento Asai, Takashi Shimomura

We study constraints on light and feebly interacting bosons with lepton flavor violation from electron beam dump experiments. Scalar, vector, and dipole interactions of the bosons…
