Description
The measurement of CP violating weak phase $\phi_s$ is achieved using the data collected by the CMS experiment at $\sqrt{s}=13$ TeV in the sample of 48500 reconstructed $B^0_s\rightarrow J/\psi \phi \rightarrow \mu^+\mu^-K^+K^-$ events corresponding to an integrated luminosity of 96.4fb$^{-1}$. The parameters are extracted by performing a time-dependent and flavor-tagged angular analysis of the $\mu^+\mu^-K^+K^-$ final state.
This talk will discuss these recent results and their combination with the previous CMS measurement at $\sqrt{s}=8$ TeV, with particular emphasis on the adopted methodology and employed novel opposite-side muon flavor tagger based on ML techniques.
