sqrt(s)=7 TeV质子-质子碰撞微分双喷流产生截面的测量

Measurement of the differential dijet production cross section in proton-proton collisions at sqrt(s)=7 TeV

CMS Collaboration

摘要:

本文测量了sqrt(s)=7 TeV质子-质子碰撞中双微分包容双喷流产生截面,它是双喷流不变质量和喷流快度的函数。这些数据对应于在LHC上用CMS探测器记录的36个反向皮巴的积分亮度。测量范围为0.2 TeV至3.5 TeV的双喷流质量和高达|y| =2.5的喷流速度。它被发现是在良好的协议与次领先阶QCD预测。

英文摘要:

A measurement of the double-differential inclusive dijet production cross section in proton-proton collisions at sqrt(s)=7 TeV is presented as a function of the dijet invariant mass and jet rapidity. The data correspond to an integrated luminosity of 36 inverse picobarns, recorded with the CMS detector at the LHC. The measurement covers the dijet mass range 0.2 TeV to 3.5 TeV and jet rapidities up to |y|=2.5. It is found to be in good agreement with next-to-leading-order QCD predictions.
