Study of CP -violating charge asymmetries of single muons and like-sign dimuons in pp¯ collisions
Year: 2014
Type: article
Abstract: We measure the inclusive single muon charge asymmetry and the like-sign dimuon charge asymmetry in $p\stackrel{\={}}{p}$ collisions using the full data set of $10.4\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ collected with the D0 detector at the Fermilab Tevatron. The standard model predictions of the charge asymmetries induced by $CP$ violation are small in magnitude compared to the current experimental precision, so nonzero measurements could indicate new sources of $CP$ violation. The measurements differ from the standard model predictions of $CP$ violation in these asymmetries with a significance of 3.6 standard deviations. These results are interpreted in a framework of $B$ meson mixing within the Cabibbo-Kobayashi-Maskawa formalism to measure the relative width difference $\mathrm{\ensuremath{\Delta}}{\mathrm{\ensuremath{\Gamma}}}_{d}/{\mathrm{\ensuremath{\Gamma}}}_{d}$ between the mass eigenstates of the ${B}^{0}$ meson system and the semileptonic charge asymmetries ${a}_{\mathrm{sl}}^{d}$ and ${a}_{\mathrm{sl}}^{s}$ of ${B}^{0}$ and ${B}_{s}^{0}$ mesons, respectively.
