Bounds reach of a future circular collider on the parameters of a minimal Baryon-Lepton symmetric model

This paper investigates the physics potential of the proton-proton Future Circular Collider (FCC-hh) in the search for a new heavy gauge boson, Z’, within the framework of the minimal Baryon-Lepton (B-L) symmetric model. We examine the exclusion limits on the mass of the Z’ boson for various sets of coupling constants, utilizing leptonic decays, specifically into charged lepton pairs (electron and muon). Using the DARKCAST framework, we compare the parameter constraints derived from previous experiments with the expected reach of the FCC-hh, providing insights into the collider sensitivity and potential to probe new physics beyond the Standard Model.
