The analysis is performed in the region of the dilepton invariant mass squared of 1.1–6.0 GeV2/c4. In addition, a test of lepton flavour universality is performed by comparing the obtained angular observables with those measured in B0 → K*0μ+μ− decays. In general, the angular observables are found to be consistent with the Standard Model expectations as well as with global analyses of other b → sℓ+ℓ− processes, where ℓ is either a muon or an electron. No sign of lepton-flavour-violating effects is observed.We express our gratitude to our colleagues in the CERN accelerator departments for the excellent performance of the LHC.
