Abstract

The inclusive D 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 mesons are used, which decay as D → ϕπ , with ϕ → K K . The measurement is performed in bins of transverse momentum, p , and rapidity, y, covering the range 2.5 < p < 25.0 GeV/c and 2.0 < y < 4.5. No kinematic dependence is observed. Evidence of nonzero D production asymmetry is found with a significance of 3.3 standard deviations.[Figure not available: see fulltext.]. s s s T T s ± ± ± ± + − ±
