Test of lepton universality with B 0 → K *0 ℓ + ℓ − decays
A test of lepton universality, performed by measuring the ratio of the branching fractions of the B 0 → K *0 μ + μ − and B 0 → K *0 e + e − decays, RK*0, is presented. The K *0 meson is reconstructed in the final state K + π − , which is required to have an invariant mass within 100 MeV/c 2 of the k...
