331 models facing new b → sμ + μ − data
331 models facing new b → sμ + μ − data
We investigate how the 331 models, based on the gauge group SU(3) C × SU(3) L × U(1)X face new data on B s,d → μ + μ − and B d → K ∗(K)μ + μ − taking into account present constraints from ΔF = 2 observables, low energy …
