New experimental results

LHCb results strengthen hints of a violation of lepton flavour universality

Theory Division

LHCb has overcome the 3 sigma barrier in the tension between the measurement of the observable RK and the prediction of the SM, reaching 3.1 sigmas. This observable tests the universality (or not) of leptonic flavor. The SM predicts a value of 1 very accurately for this observable.

Marcel Algueró on behalf of the group led by Joaquim Matias presented the implications of this new data in the global analyzes of observables governed by b-> sll in the (virtual) conference of Moriond QCD 2021.
