Dark matter contribution to b → sμ+μ− anomaly in local U(1)Lμ−Lτ model
We propose a local U(1)Lμ−Lτ model to explain b→sμ+μ− anomaly observed at the LHCb and Belle experiments. The model also has a natural dark matter candidate N. We introduce SU(2)L-doublet colored scalar q˜ to mediate b→s transition at one-loop level. The U(1)Lμ−Lτ gauge symmetry is broken spontaneou...
