Measurement of the CP-violating phase ${\varphi }_s^{J/\psi \varphi }$ using the flavor-tagged decay $B_s^0\to J/\psi \varphi$ in 8 fb${}^{-1}$ of $p \barp$ collisions

Abstract

We report an updated measurement of the CP-violating phase, ${\varphi }_s^{J/\psi \varphi }$, and the decay-width difference for the two mass eigenstates, $\Delta {\Gamma }_s$, from the flavor-tagged decay $B_s^0\to J/\psi \varphi$. The data sample corresponds to an integrated luminosity of 8.0 fb${}^{-1}$ accumulated with the D0 detector using $p \barp$ collisions at $\sqrt{s}=1.96$ TeV produced at the Fermilab Tevatron collider. The 68% confidence level intervals, including systematic uncertainties, are $\Delta {\Gamma }_s=0.163+0.065-0.064p{s}^{-1}$ and ${\varphi }_s^{J/\psi \varphi }=-0.55+0.38-0.36$. The $p$-value for the Standard Model point is 29.8%.
