 Experimental status of CPV in $B_s^0$ mixing / Mejia Guisao, Jhovanny Andres (Antioquia U.) This proceeding contribution presents the latest measurement of the CP-violation and other physics parameters in the $B_s^0 \to J/\psi \phi$ decay channel performed by the ATLAS, CMS and LHCb experiments. [...] arXiv:2008.08199. - 2020. - 9 p. 00000 Contours of 68\% confidence level in the \phis-\DGs{} plane, showing ATLAS results for 7 TeV and 8 TeV data (blue dashed-dotted curve), for 13 TeV data (green dashed curve) and for 13 TeV data combined with 7 TeV and 8 TeV (red solid curve) data. The Standard Model prediction is shown as a very thin black rectangle. In all contours the statistical and systematic uncertainties are combined in quadrature and correlations are taken into account. Taken from~\cite{ref:cpvATLAS}. - 00001 The two-dimensional likelihood contours at 68\% CL in the \phis-\DGs{} plane, for the CMS 8~TeV (dashed green line), 13~TeV (dashed blue line), and the combined (solid red line) results.
