全息QCD中高能质子-质子散射的微分截面和总截面

Differential and total cross sections of high energy proton-proton scattering in holographic QCD

Akira Watanabe

摘要:

在全息QCD的框架下,对高能质子-质子散射进行了分析,重点讨论了Regge区,并考虑了Pomeron交换来描述所涉及的非微扰动力学。我们结合Regge化自旋2粒子传播子和由自底向上AdS/QCD模型得到的质子引力形状因子,计算了微分截面和总截面.我们明确地证明了我们的计算和目前可用的实验数据,包括最近的测量在$\sqrt{s} = 13$ TeV的TOTEM合作在大型强子对撞机之间的比较。结果表明,我们的结果是一致的数据,这意味着本框架的工作在考虑TeV规模。

英文摘要:

The analysis on the high energy proton-proton scattering is presented, focusing on the Regge regime and considering the Pomeron exchange to describe the involved nonperturbative dynamics in the framework of holographic QCD. We combine the Reggeized spin-2 particle propagator and the proton gravitational form factor, which is obtained from the bottom-up AdS/QCD model, and calculate the differential and total cross sections. We explicitly demonstrate the comparison between our calculations and the currently available experimental data including the recent ones measured at $\sqrt{s} = 13$ TeV by the TOTEM collaboration at the LHC. It is shown that our results are consistent with the data, which implies that the present framework works in the considered TeV scale.
