Kingman Cheung, Thong T. Q. Nguyen, C. J. Ouseph

TL;DR
This paper evaluates the potential of the Forward Physics Facility experiments to detect vector leptoquarks across a broad mass range, highlighting FLArE (100 tons) as the most sensitive detector.
Contribution
It provides the first detailed sensitivity analysis of multiple FPF experiments for vector leptoquark detection over a wide mass spectrum.
Findings
FLArE (100 tons) has the highest sensitivity among the experiments.
Sensitivity decreases as leptoquark mass increases.
Combined neutrino interaction channels improve detection prospects.
Abstract
In this study, we calculate the sensitivity reach on the vector leptoquark (LQ) at the experiments proposed in Forward Physics Facility (FPF), including FASER, FASER, FLArE (10 tons), and FLArE (100 tons) using the neutrino-nucleon scattering ( and ). We cover a wide mass range of GeV 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.
