Description

The angular analysis of the rare decay Bs0 → phi mu mu is performed in bins of squared dimuon invariant mass (q2), using an integrated luminosity of 137.5 fb-1 of data collected by the CMS detector at center-of-mass energy, √s = 13 TeV. The CP asymmetry (A6) and CP averaged (FL) angular observables are measured to be in agreement with the Standard Model prediction in the low q2 region 1.1-6.0 GeV2 /c4, using Run II pseudo-data sample. Results using data are blinded at present. Pseudo-data results are available.
