Flavor non-universal gauge interactions and anomalies in B-meson decaysSupported by the Grant-in-Aid for Innovative Areas (16H06490) / Tang, Yong ; Wu, Yue-Liang
Motivated by flavor non-universality and anomalies in semi-leptonic B-meson decays, we present a general and systematic discussion about how to construct anomaly-free U(1)′ gauge theories based on an extended standard model with only three right-handed neutrinos. [...]
