Title: Back to the Standard Lore: About the LHCb Anomaly and the Galactic Center Excess

Abstract:
There is a general remarkable agreement between current generation experimental data and our understanding of the fundamental physics behind. On the other hand, theoretical arguments in favor of a natural theory point towards the existence of New Physcis (NP) nearby the electroweak scale, possibly also correlated to the presence of Dark Matter (DM) in our Universe, greatly supported by e.g. the cosmological precision era we are living in.
Bearing all this in mind, we critically re-examine two NP hints widely debated these days, namely the LHCb anomaly, concerning a 3.7 sigma deviation in the angular analysis of the rare decay mode B –> K* mu mu, and the evidence of a roughly spherical gamma-ray excess at the Galactic Center, well-fitted by a DM component added on top of the standard galactic diffuse emission.
The aim of the talk is to highlight the importance of some ordinary known physics, misinterpreted or underestimated so far in the literature, that may actually play a crucial role in determining the goodness of these NP claims.
Indeed, for the aforementioned cases under study we eventually show that no real tension between theory and experiments arises when well-motivated standard physics is properly taken into account.
