Measurement of $CP$ violation and the $B_s^0$ meson decay width difference with $B_s^0 \to J/\psi K^+K^-$ and $B_s^0\to J/\psi\pi^+\pi^-$ decays

The time-dependent $CP$ asymmetry in $B_s^0\to J/\psi K^+K^-$ decays is measured using $pp$ collision data at $\sqrt{s}=7$TeV, corresponding to an integrated luminosity of 1.0$fb^{-1}$, collected with the LHCb detector. The decay time distribution is characterised by the decay widths $\Gamma_{\mathr...
