Measurement of CP violation in B0→ D∗±D∓ decays

The decay-time-dependent CP asymmetry in B0→ D∗±D∓ decays is mea- sured using a data set corresponding to an integrated luminosity of 9 fb−1 recorded by the LHCb detector in proton-proton collisions at centre-of-mass energies of 7, 8 and 13 TeV. The CP parameters are measured asSD∗D=−0.861±0.077stat±0.019syst,ΔSD∗D=0.019±0.075stat±0.012syst,CD∗D=−0.059±0.092stat±0.020syst,ΔCD∗D=−0.031±0.092stat±0.016syst,AD∗D=0.008±0.014stat±0.006syst.\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ {\displaystyle \begin{array}{c}{S}_{D\ast D}=-0.861\pm 0.077\left(\mathrm{stat}\right)\pm 0.019\left(\mathrm{syst}\right),\\ {}\varDelta {S}_{D\ast D}=0.019\pm 0.075\left(\mathrm{stat}\right)\pm 0.012\left(\mathrm{syst}\right),\\ {}{C}_{D\ast D}=-0.059\pm 0.092\left(\mathrm{stat}\right)\pm 0.020\left(\mathrm{syst}\right),\\ {}{\varDelta C}_{D\ast D}=-0.031\pm 0.092\left(\mathrm{stat}\right)\pm 0.016\left(\mathrm{syst}\right),\\ {}{\mathcal{A}}_{D\ast D}=\kern0.75em 0.008\pm 0.014\left(\mathrm{stat}\right)\pm 0.006\left(\mathrm{syst}\right).\end{array}} $$\end{document}
