"Table 5c" of "Measurements of $B \rightarrow J/\psi$ at forward rapidity in $p+p$ collisions at $\sqrt{s}=510$ GeV"

The $b\bar{b}$ cross section per unit rapidity ($d\sigma/dy(pp→b\bar{b})$) extracted from the obtained $F_{B \rightarrow J/\psi}$ and the PHENIX inclusive $J/\psi$ cross section measured at 200 GeV scaled with color-evaporation-model calculations, at the mean $B$ hadron rapidity.

背景概述

该数据集来自PHENIX合作组，测量了在√s=510 GeV的p+p碰撞中B介子衰变产生的J/ψ的分数，并提取了bb-bar产生截面。表5c给出了在快度y=±1.7处每单位快度的bb-bar截面为3.63+1.92-1.70 μb，包含统计和系统误差，用于验证理论模型并与其他实验比较。
