Abstract :

The LHCb collaboration has reported deviations from the standard model (SM) in b � s`+`� decays. These can be explained within U(1)0 gauge extensions of the SM, in which the corresponding Z0 gauge boson can mediate b � s`+`� transitions at tree level. In these models SM fermions carry family-dependent U(1)0 charges in order to generate the required flavor changing Z0 to quarks and lepton non-universality. We showed that such models can also accommodate a dark sector and the dark matter candidates can annihilate efficiently to produce the observed relic density. A big class of models to explain the flavor anomalies contains hypothetical particle leptoquarks. We correlate such models to the s-channel enhancement of neutrinoquark scattering in the very high energy shower events observed by the IceCube collaboration.
