Measurement of the CP violating weak phase $\phi_s$ in the $\mathrm{B}^0_\mathrm{s}\to\mathrm{J}/\psi\phi \to \mu^{+}\mu^{-}\mathrm{K^+K^-}$ decay process using the data collected by CMS in proton-proton collision at $\sqrt{s} = 13\,\text{TeV}$
The invariance of the decay rate ( the amplitude square) of a decay process $|\mathcal{M}|^2(|{\psi_1}\rangle\to |{\psi_2}\rangle) $ under the simultaneous operation of discrete symmetry operators such as charge conjugation ($\hat{C}$), and parity ($\hat{P}$) is defined as the CP-symmetry i.e., $...
