| Abstract: | A full set of optimized observables is measured in an angular analysis of the decay ⁎ using a sample of proton-proton collisions at , collected with the CMS detector at the LHC, corresponding to an integrated luminosity of 140 . The analysis is performed in six bins of the squared invariant mass of the dimuon system, , over the range . 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. |
