Resolving $B$-meson anomalies by flavor-dependent gauged symmetries $\prod _{i=1}^{3}U(1{)}_{B_i-L_i}$

Abstract

We propose a model with flavor dependent gauged symmetries of $\prod _{i=1}^{3}U(1{)}_{B_i-L_i}$ with $i$ the family indices. After formulating the renormalizable Yukawa Lagrangian, Higgs potential and kinetic term, we study the lepton sector based on a successful two-zero texture without introducing extra scalar bosons to avoid the dangerous Goldstone bosons. In particular, we discuss the muon related phenomenologies via additional neutral gauge bosons. In our numerical analysis, we explore the allowed parameter space, in which the anomaly of $B\to K^{\ast }\bar{\mu }\mu$ can be explained.
