| dc.description.abstract | The CP-violating weak phase of the meson and the decay width difference of the light and heavy mass eigenstates are measured with the CMS detector at the LHC using a data sample of decays. The analysed data set corresponds to an integrated luminosity of collected in pp collisions at a centre-of-mass energy of . A total of 49 200 reconstructed decays are used to extract the values of and by performing a time-dependent and flavour-tagged angular analysis of the final state. The weak phase is measured to be , and the decay width difference is . | en_US |
