Abstract
The CPviolating weak phase \phi_\mathrm{s}and the decay width difference \Delta\Gamma_\mathrm{s}between the light and heavy B^0_\mathrm{s}mass eigenstates are measured with the CMS detector at the LHC in a sample of 48 500 reconstructed B^0_\mathrm{s}\toJ/\psi\, \phi1020) \to\mu^+\mu^-^+^-events. The measurement is based on a data sample corresponding to an integrated luminosity of 96.4 fb^{-1} collected in...
