Abstract：
We propose a new model with flavor-dependent gauged U(1)_B-L₁×U(1)_B-L₂-L₃ symmetry in addition to the flavor-blind symmetry in the Standard Model. The model contains three right-handed neutrinos to cancel gauge anomalies and several Higgs bosons to construct the measured fermion masses. We show the generic features of the model and explore its phenomenology. In particular, we discuss the current bounds on the extra gauge bosons from the K and B meson mixings as well as the LEP and LHC data, and focus on their contributions to the lepton flavor violating processes of l_i+1→l_iγ (i=1,2).
- flavor-dependent gauged Abelian symmetries ,
- model building ,
- numerical analysis of gauge boson masses and coupling
