Measurement of the direct CP-violating charge asymmetry in Ds?? decays
Original language description
We present a measurement of the direct CP-violating charge asymmetry in Ds?? decays where the ? meson decays to K+K, using the full Run II data set with an integrated luminosity of 10.4 fb1 of proton-antiproton collisions collected using the D0 detectorat the Fermilab Tevatron Collider. The normalised difference ACP in the yield of D+s and Ds mesons in these decays is measured by fitting the difference between their reconstructed invariant mass distributions. This results in an asymmetry of ACP=[0.380.27], which is the most precise measurement of this quantity to date. The result is consistent with the standard model prediction of zero CP asymmetry in this decay. Updated to include changes made after referees comments. Corrected an affiliation in theauthor list.
