Diquark explanation of b→sℓ+ℓ-

Abstract

The discrepancies between b→sℓ+ℓ− data and the corresponding Standard Model predictions point to the existence of new physics with a significance at the 5σ level. While previously a lepton flavor universality violating effect was preferred, the new R(K(*)) and Bs→μ+μ− measurements are now compatible with the Standard Model, favoring a lepton flavor universal beyond the Standard Model contribution to C9. Since heavy new physics is generally chiral, and because of the stringent constraints from charged lepton flavor violation, this pose Show more
