Recent anomalies in B meson decays observed by the LHCb collaboration have motivated the construction of extensions of the Standard Model with a gauged family non-universal U(1) factor. I will present a large class of family non-universal U(1) gauge models for which flavor changing neutral currents are completely controlled by CKM matrix elements. I will discuss then phenomenological...

Updating various theoretical and experimental constraints on the four different types of two-Higgs-doublet models (2HDMs), we find that only the ``lepton-specific" (or ``type X") 2HDM can explain the present muon g−2 anomaly in the parameter region of large tanβ, a light CP-odd boson, and heavier CP-even and charged bosons which are almost degenerate. The severe constraints on the models come...

The analysis of the full LHC Run I data set of proton-proton collision events collected with the LHCb detector, corresponding to an integrated luminosity of 3.0 fb-1, is yielding several improved results on exotic hadron candidates, such as $X(3872)$ and $Z(4430)^+$, as well as the first observation of two new states compatible with the pentaquark hypothesis. Run II data allow LHCb to further...
