$CP$ violation and CKM studies (and first LHCb Run II results)

The LHC is the new $b$-hadron factory and will be dominating flavour physics until the start of Belle II, and beyond in many decay modes. While the $B$ factories and Tevatron experiments are still analysing their data, ATLAS, CMS and LHCb are producing interesting new results in $CP$ violation and rare decays, that set strong constraints on models beyond that SM and exhibit some discrepancies with the SM predictions. The LHCb collaboration used the LHC 50 ns ramp-up period of July 2015 to measure the double-differential $J/\psi$, $J/\psi$-from-$b$-hadron and charm crosssections at $\sqrt s$ = 13 TeV. Both measurements were performed directly on triggered candidates using a reduced data format that does not require offline processing
