Measurement of CP Violation in ${\mathrm{B}}_{\mathrm{s}}^0\to \mathrm{J}/\psi \varphi$ decays with the CMS detector

Jacopo Pazzini

The CP-violating weak phase ${\varphi }_{\mathrm{s}}$ and the decay width difference $\Delta {\Gamma }_{\mathrm{s}}$ of ${\mathrm{B}}_{\mathrm{s}}^0$ mesons are measured by the CMS experiment at the LHC us…
