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.B-physicsCMSFlavor anomaliesHeavy flavorRare decaysjournal article10.1016/j.physletb.2025.139406
