Test of Lepton Flavor Universality with B0 →k∗0l+l- Decays at Large Dilepton Invariant Mass
Aaij R., Abdelfatah M., Abdelmotteleb A. S. W., Abellan Beteta C. et autres
Muon-electron universality is tested in B0→K∗0l+l- decays, in the dilepton-invariant-mass region above the ψ(2S) resonance. The analysis uses beauty mesons produced in proton-proton collisions recorded by the LHCb detector at center-of-mass energies of 7, 8, and 13 TeV, corresponding to an integrated …
