Dark matter and B-meson anomalies in a flavor dependent gauge symmetry
Original language description
A possibility of explaining the anomalies in the semileptonic B-meson decay B->K*μμ has been explored in the framework of the gauged U(1)μ-τ symmetry. Apart from the muon anomalous magnetic moment and neutrino sector, we formulate the model starting with a valid Lagrangian and consider the constraints from the neutral meson mixings, the bounds on direct detection and the relic density of the bosonic dark matter candidate augmented to collider constraints. We search the parameter space, which accommodate the size of the anomaly of the B->K*μμ decay, to satisfy all experimental constraints. We found the allowed region on the plane of the dark matter and Z' masses is rather narrow compared to the previous analysis.
