Electron beam dump constraints on light bosons with lepton flavor violating couplings

A bstract We study constraints on light and feebly interacting bosons having charged lepton flavor violating couplings from electron beam dump experiments. Scalar, pseudoscalar, vector, and dipole type interactions of the bosons are analyzed, and excluded regions from the searches for decays into el...

Summary:A bstract We study constraints on light and feebly interacting bosons having charged lepton flavor violating couplings from electron beam dump experiments. Scalar, pseudoscalar, vector, and dipole type interactions of the bosons are analyzed, and excluded regions from the searches for decays into electron-positron pairs are derived. It is found that parameter regions unconstrained by flavor violating decays of muon can be excluded using the results of the E137 experiment. We also discuss the impact of the search for flavor violating decays of the light bosons in electron beam dump experiments.
