在 s=200 GeV 的 p+p 碰撞中，来自重味（魅力和底部）衰变的电子动量分布，在 s=200 GeV 下的中速 |y|< 0.35 已通过 BNL 相对论重离子对撞机的 PHENIX 实验在横向动量范围 0.3 < p(T)< 9 GeV/c 上测量。使用两种独立的方法来测定重口味产量，结果彼此吻合良好。固定阶加下一个对数扰动 QCD 计算与理论和实验不确定性内的数据一致，0.3 < p(T)< 9 GeV/c 时数据/理论比为 1.71 +/- 0.02(stat)+/- 0.18(sys)。该能量下的总魅力产生截面也被推导为 sigma(cc)=567 +/- 57(stat)+/- 193(sys) mu b。
The momentum distribution of electrons from decays of heavy flavor (charm and bottom) for midrapidity |y|< 0.35 in p+p collisions at s=200 GeV has been measured by the PHENIX experiment at the BNL Relativistic Heavy Ion Collider over the transverse momentum range 0.3 < p(T)< 9 GeV/c. Two independent methods have been used to determine the heavy-flavor yields, and the results are in good agreement with each other. A fixed-order-plus-next-to-leading-log perturbative QCD calculation agrees with the data within the theoretical and experimental uncertainties, with the data/theory ratio of 1.71 +/- 0.02(stat)+/- 0.18(sys) for 0.3 < p(T)< 9 GeV/c. The total charm production cross section at this energy has also been deduced to be sigma(cc)=567 +/- 57(stat)+/- 193(sys) mu b.
