Description

Significant deviations from SM predictions have been observed in $ b \to s \mu^+ \mu^-$ decays and in the muon (g-2). Scalar leptoquark extensions of the SM are known to be able to address these anomalies, but generically give rise to lepton flavor violation or even proton decay. A possible resolution is to introduce a lepton-flavored U(1) gauge symmetry to preserve the accidental symmetries of the SM. I will discuss various approaches to addressing the anomalies in this framework, with a particular focus on constraining the light gauge boson solution to the g-2. I will also touch on a surprisingly strong protection mechanism preventing proton decay in the presence of a lepton-flavored symmetry
