在sqrt{s} = 1.96 TeV的p-pbar碰撞中光子和b夸克喷注的联合产生

A study of the associated production of photons and b-quark jets in p-pbar collisions at sqrt{s} = 1.96 TeV

CDF collaboration

摘要:

在$\sqrt{s}=1.96$ TeV的质子反质子碰撞中,测量了至少一个含有$b$ -夸克强子的喷注的光子产生截面.该分析使用对应于由CDF II探测器收集的340 pb $^{-1}$积分光度的数据样本。测量了微分截面与光子横向能量$E_T^γ$、$d σ$($p \overline{p} \to γ+ \geq 1 b$ -jet)/ $d E_T^γ$和总截面$σ$($p \overline{p} \to γ+ \geq 1 b$ -jet; $E_T^γ> 20$ GeV)的关系。下一个领先的顺序预测的过程中的比较。

英文摘要:

The cross section for photon production in association with at least one jet containing a $b$-quark hadron has been measured in proton antiproton collisions at $\sqrt{s}=1.96$ TeV. The analysis uses a data sample corresponding to an integrated luminosity of 340 pb$^{-1}$ collected with the CDF II detector. Both the differential cross section as a function of photon transverse energy $E_T^γ$, $d σ$($p \overline{p} \to γ+ \geq 1 b$-jet)/$d E_T^γ$ and the total cross section $σ$($p \overline{p} \to γ+ \geq 1 b$-jet; $E_T^γ> 20$ GeV) are measured. Comparisons to a next-to-leading order prediction of the process are presented.
