Abstract

Abstract: The inclusive D± s production asymmetry is measured in pp collisions collected by the LHCb experiment at centre-of-mass energies of √ s = 7 and 8 TeV. Promptly produced D± s mesons are used, which decay as D± s → φπ±, with φ → K+K−. The measurement is performed in bins of transverse momentum, pT, and rapidity, y, covering the range 2.5 < pT < 25.0 GeV/c and 2.0 < y < 4.5. No kinematic dependence is observed. Evidence of nonzero D± s production asymmetry is found with a significance of 3.3 standard deviations.
