QCD硬过程中的双射流方位角关联

Dijet Azimuthal Correlations in QCD Hard Processes

Yazid Delenda

摘要:

研究了QCD硬过程中双喷注产生的方位角关联分布。这个观测值对背靠背区域中的软和/或共线发射敏感,从而产生单次和双次发射。我们提供了在HERA的DIS和强子碰撞在Tevatron的NLL精度的预测,并进行NLO匹配NLOJET++结果在DIS的情况下。

英文摘要:

We study the azimuthal correlation distribution for dijet production in QCD hard processes. This observable is sensitive to soft and/or collinear emissions in the back-to-back region, giving rise to single and double logarithms. We provide resummed predictions to NLL accuracy for both DIS at HERA and hadronic collisions at Tevatron and perform a NLO matching to NLOJET++ results in the DIS case.
