HIGHLIGHTS
- who: Kristof De Bruyn from the Centre de Physique des Particules de Marseille (CPPM), de Luminy, Marseille, France have published the paper: Tests of Lepton Universality at LHCb, in the Journal: (JOURNAL)
- future: But certain extensions of the SM like models involving a Z boson or leptoquarks need not couple equally to electrons and muons thus leading to a value of RK that is different from one.
SUMMARY
This report presents the measurements of the ratios of branching fractions RK and R(D* ), as well as preliminary upper limits on the . . .
