The measured parameters include the $CP$-violating phase $\\phi_s$, the width difference $\\Delta\\Gamma_{s}$ between the $B^0_s$ meson mass eigenstates and the average decay width $\\Gamma_{s}$. The values measured for the physical parameters are combined with those from 19.2 $\\mathrm{fb}^{-1}$ of 7 TeV and 8 TeV data, leading to the following:\n\\begin{eqnarray*}\n\\phi_s & = & -0.087\\phantom{0} \\pm 0.036\\phantom{0} ~\\mathrm{(stat.)} \\pm 0.021\\phantom{0} ~\\mathrm{(syst.)~rad} \\\\\n\\Delta\\Gamma_{s} & = & \\phantom{-}0.0657 \\pm 0.0043 ~\\mathrm{(stat.)} \\pm 0.0037 ~\\mathrm{(syst.)~ps}^{-1} \\\\\n\\Gamma_{s} & = & \\phantom{-}0.6703 \\pm 0.0014 ~\\mathrm{(stat.)} \\pm 0.0018 ~\\mathrm{(syst.)~ps}^{-1} \\\\\n\\end{eqnarray*}\nResults for $\\phi_s$ and $\\Delta\\Gamma_{s}$ are also presented as 68\\% confidence level contours in the $\\phi_s$--$\\Delta\\Gamma_{s}$ plane. Furthermore, the transversity amplitudes and corresponding strong phases are measured. $\\phi_s$ and $\\Delta\\Gamma_{s}$ measurements are in agreement with the Standard Model predictions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.103066.v1/t1","@type":"Dataset","description":"Fitted values for the physical parameters of interest with their statistical and systematic uncertainties, for the result of solution (a).","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.103066.v1/t2","@type":"Dataset","description":"Fitted values for the physical parameters of interest with their statistical and systematic uncertainties, for the result of solution (b).","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.103066.v1/t3","@type":"Dataset","description":"Fit correlations between the physical parameters of interest, obtained from the fit for solution (a).","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.103066.v1/t4","@type":"Dataset","description":"Fit correlations between the physical parameters of interest, obtained from the fit for solution (b).","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.103066.v1/t5","@type":"Dataset","description":"Values of the physical parameters extracted in the combination of solution (a) of 13 TeV results with those obtained from...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.103066.v1/t6","@type":"Dataset","description":"Values of the physical parameters extracted in the combination of solution (b) of 13 TeV results with those obtained from...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.103066.v1/t7","@type":"Dataset","description":"Correlation matrix of the BLUE combination of the 7 TeV and 8 TeV results and the solution (a) of the...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.103066.v1/t8","@type":"Dataset","description":"Correlation matrix of the BLUE combination of the 7 TeV and 8 TeV results and the solution (b) of the...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.103066.v1/t9","@type":"Dataset","description":"Summary of systematic uncertainties assigned to the physical parameters of interest.","name":"Table 9"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1776624?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/103066"}],"inLanguage":"en","name":"Measurement of the $CP$-violating phase $\\phi_s$ in $B^0_s \\to J/\\psi\\phi$ decays in ATLAS at 13 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1776624?version=1","version":1}
