A multi-charged particle model with local U(1)(mu-tau) to explain muon g-2, flavor physics, and possible collider signature

We consider a model with multi-charged particles, including vector-like fermions, and a charged scalar under a local U(1)(mu-tau) symmetry. We search for an allowed parameter region explaining muon anomalous magnetic moment (muon g - 2) and b -> sl(+)l(-) anomalies, satisfying constraints from the lepton flavor violations, Z boson decays, meson anti-meson mixing, and collider experiments. Via numerical analysis, we explore the typical size of the muon g - 2 and Wilson coefficients to explain the b -> sl(+)l(-) anomalies in our model when all other experimental constraints are satisfied. Subsequently, we discuss the collider physics of the multicharged vectorlike fermions, considering a number of benchmark points in the allowed parameter space.
