Measurement of $D{_s}{^\pm}$ production asymmetry in pp collisions at $\sqrt s$ = 7 and 8 TeV


LHCb Collaboration; Bernet, R; Müller, K; Serra, N; Steinkamp, O; Straumann, U; Vollhardt, A; et al (2018). Measurement of $D{_s}{^\pm}$ production asymmetry in pp collisions at $\sqrt s$ = 7 and 8 TeV. Journal of High Energy Physics, 08:008.

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.
