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…

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…

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…

Resolving the Hubble tension in a U(1) model with Majoron

Takeshi Araki, Kento Asai, Kei Honda +4

In this paper, we explore possibilities of resolving the Hubble tension and anomaly simultaneously in a U(1) model with Majoron. We only focus on a case wher…

Dark Photon from Light Scalar Boson Decays 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 focus on dark photon associating with an additional U(1…

Enhancement of the Transition Magnetic Moments of a Neutrino by Degenerate Electrons

Hisashi Kikuchi

The one-loop induced magnetic dipole moments of a neutrino are examined in a background of degenerate electrons in the standard model. For the nonrelativistic neutrino, they are en…

Decay of Z into Two Light Higgs Bosons

T. V. Duong, E. Keith, Hisashi Kikuchi +1

If the standard electroweak gauge model is extended to include two or more Higgs doublets, there may be a neutral Higgs boson which is light (with a mass of say 10 GeV) but the…
