摘要
In this study, we calculate the sensitivity reach on the vector leptoquark (LQ) U1 at the experiments proposed in the Forward Physics Facility (FPF), including FASERν, FASERν2, FLArE (10 tons), and FLArE (100 tons) using the neutrino-nucleon scattering (νN→νN′ and νN→lN′). We cover a wide mass range of 10-3 GeV≤MLQ≤104 GeV. The new result shows that the FLArE (100 tons) offers the best sensitivity to the LQ model. The sensitivity curves for all the experiments follow a similar pattern with weakened sensitivities with the increment of the LQ mass. We combine the sensitivities obtained from the neutral- and charged-current interactions of the neutrinos.
