Thermal WIMP, muon g-2 and B^+ \to K^+ \nu \bar{\nu} in U(1)_{L_\mu - L_\tau} models

I will talk about dark matter and flavor physics within U(1)_{L_\mu - L_\tau} models, emphasizing the difference between the massive Z’ without and with the dark Higgs boson. The topics include thermal WIMP, the muon g-2 and the mild excess in the missing energy in B^+ \rightarrow K^+ \nu\bar{\nu} reported by the Belle II Collaboration.
