N2 - We present a measurement of the direct CP-violating charge asymmetry in D+s→ϕπ± decays where the ϕ meson decays to K+K−, using the full Run II data set with an integrated luminosity of 10.4  fb−1 of proton-antiproton collisions collected using the D0 detector at the Fermilab Tevatron Collider. The normalized difference ACP in the yield of D+s and D−s mesons in these decays is measured by fitting the difference between their reconstructed invariant mass distributions. This results in an asymmetry of ACP=[−0.38±0.27]%, 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.
