在LHC的喷气式飞机否决

Jet vetoing at the LHC

Jeffrey Forshaw, James Keates, Simone Marzani

摘要:

我们研究了否决权对LHC中一对高横向动量喷流之间的快度区附加喷流的影响。我们的目标是总结最重要的喷流横向动量的否决规模的比率,并为此目的,我们试图评估的意义,出现在高阶微扰膨胀的超级领先的微扰。我们还比较了我们的结果HERWIG++,在试图确定角有序部分子簇射的准确性。我们发现,有足够大的喷流横动量作为库仑胶子交换的后果,出现大的修正。

英文摘要:

We study the effect of a veto on additional jets in the rapidity region between a pair of high transverse momentum jets at the LHC. We aim to sum the most important logarithms in the ratio of the jet transverse momentum to the veto scale and to that end we attempt to assess the significance of the super-leading logarithms that appear at high orders in the perturbative expansion. We also compare our results to those of HERWIG++, in an attempt to ascertain the accuracy of the angular ordered parton shower. We find that there are large corrections that arise for large enough jet transverse momenta as a consequence of Coulomb gluon exchanges.
