Probing millicharged particles with NA64 experiment at CERN

In this paper we estimate the sensitivity of the NA64 experiment to millicharged particles (χ). That experimental facility is dedicated to the searching for dark sector particles in missing energy events at the CERN SPS. We consider missing momentum signatures in the ≃100  GeV electron and muon beam...

Sumario:In this paper we estimate the sensitivity of the NA64 experiment to millicharged particles (χ). That experimental facility is dedicated to the searching for dark sector particles in missing energy events at the CERN SPS. We consider missing momentum signatures in the ≃100  GeV electron and muon beams and show that the later one allows to obtain more stringent bounds on the millicharge Qχ, which for the χ masses 100  MeV≤mχ≤500  MeV at the level Qχ/e≲O(10-3)-O(10-2).
