Özet

A full set of optimized observables is measured in an angular analysis of the decay B⁰→K^⁎(892)⁰μ⁺μ⁻ using a sample of proton-proton collisions at s=13TeV, collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 140 fb⁻¹. The analysis is performed in six bins of the squared invariant mass of the dimuon system, q², over the range 1.1<q²<16GeV². The results are among the most precise experimental measurements of the angular observables for this decay and are compared to a variety of predictions based on the standard model. Some of these predictions exhibit tension with the measurements.
