强子碰撞中喷注之间的间隙

Gaps between jets in hadronic collisions

O. Kepka, C. Marquet, C. Royon

摘要:

我们提出了一个模型来描述强子-强子碰撞中的衍射事件,其中一个快度间隙被两个喷流包围。在t通道中交换的硬色单重态对象和快度间隙由pQCD Balitsky-Fadin-Kuraev-Lipatov Pomeron描述,包括由于下一个领先的修正。我们允许快度间隙小于喷流间的快度间隔,并使用HERWIG Monte Carlo模拟了相应的软辐射。我们的模型是能够重现所有的Tevatron数据,并允许估计在大型强子对撞机的喷流-间隙-喷流截面。

英文摘要:

We propose a model to describe diffractive events in hadron-hadron collisions where a rapidity gap is surrounded by two jets. The hard color-singlet object exchanged in the t-channel and responsible for the rapidity gap is described by the pQCD Balitsky-Fadin-Kuraev-Lipatov Pomeron, including corrections due to next-to-leading logarithms. We allow the rapidity gap to be smaller than the inter-jet rapidity interval, and the corresponding soft radiation is modeled using the HERWIG Monte Carlo. Our model is able to reproduce all Tevatron data, and allows to estimate the jet-gap-jet cross section at the LHC.
