Description

In my talk I will discuss the latest LHCb results and implications from the rare B and strange decays. Run1 of LHC has finished. The first results from Run 2 are announced every month. No definitive evidence has been found for New Physics at the TeV scale despite the compelling theoretical arguments. But the situation is far from dull - not all the anomalies have vanished with the additional data and there are several serious tensions in the B-decays that remain to be understood and should not be taken lightly. I will focus on the tensions driven by the exclusive and inclusive $b\rightarrow s l^+l^-(\gamma) $ modes. I will address one of the possible scenarios where the tensions are treated as underestimated Standard Model resonance effects and present results from a new LHCb $B^+ \rightarrow K^+ \mu^+ \mu^- $ measurement including these resonance effects. I will also show the very fresh Run 2 results from the fully leptonic B decays and discuss their implications on the (pseudo)scalar Wilson coefficients.
