A full set of optimized observables is measured in an angular analysis of the decay B&sup(0) *> K&sup(∗ )(892)&sup(0)*m&sup(+)*m&sup(−) 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&sup(−1). The analysis is performed in six bins of the squared invariant mass of the dimuon system, 𝑞&sup(2), over the range 1.1 < 𝑞&sup(2) < 16GeV&sup(2). 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.
