Title: Measurements of μ μ pairs from open heavy flavor and Drell-Yan in p + p collisions at s = 200 GeV

Abstract

PHENIX reports differential cross sections of μμ pairs from semileptonic heavy-flavor decays and the Drell-Yan production mechanism measured in p+p collisions at s =200 GeV at forward and backward rapidity (1.2<|η|<2.2). The μμ pairs from $$c\bar{c}, b\bar{b}$$, and Drell-Yan are separated using a template fit to unlike- and like-sign muon pair spectra in mass and pT. The azimuthal opening angle correlation between the muons from $$c\bar{c}$$ and $$b\bar{b}$$ decays and the pair-pT distributions are compared to distributions generated using pythia and powheg models, which both include next-to-leading order processes. The measured distributions for pairs from $$c\bar{c}$$ are consistent with pythia calculations. The $$c\bar{c}$$ data present narrower azimuthal correlations and softer pT distributions compared to distributions generated from powheg. The $$b\bar{b}$$ data are well described by both models. The extrapolated total cross section for bottom production is 3.75±0.24(stat)±$$_{0.50}^{0.35}$$(syst)±0.45(global) [μb], which is consistent with previous measurements at the Relativistic Heavy Ion Collider in the same system at the same collision energy and is approximately a factor of 2 higher than the central value calculated with theoretical models. The measured Drell-Yan cross section is in good agreement with next-to-leading-order quantum-chromodynamics calculations.

abstractNote = {PHENIX reports differential cross sections of μμ pairs from semileptonic heavy-flavor decays and the Drell-Yan production mechanism measured in p+p collisions at s =200 GeV at forward and backward rapidity (1.2<|η|<2.2). The μμ pairs from $c\bar{c}, b\bar{b}$, and Drell-Yan are separated using a template fit to unlike- and like-sign muon pair spectra in mass and pT. The azimuthal opening angle correlation between the muons from $c\bar{c}$ and $b\bar{b}$ decays and the pair-pT distributions are compared to distributions generated using pythia and powheg models, which both include next-to-leading order processes. The measured distributions for pairs from $c\bar{c}$ are consistent with pythia calculations. The $c\bar{c}$ data present narrower azimuthal correlations and softer pT distributions compared to distributions generated from powheg. The $b\bar{b}$ data are well described by both models. The extrapolated total cross section for bottom production is 3.75±0.24(stat)±$_{0.50}^{0.35}$(syst)±0.45(global) [μb], which is consistent with previous measurements at the Relativistic Heavy Ion Collider in the same system at the same collision energy and is approximately a factor of 2 higher than the central value calculated with theoretical models. The measured Drell-Yan cross section is in good agreement with next-to-leading-order quantum-chromodynamics calculations.},
