LHC的振幅和横截面

Amplitudes and Cross Sections at the LHC

Errol Gotsman

摘要:

我们描述的GLM模型,成功地描述了软强子相互作用的能量从ISR到LHC的元素。这个模型是基于一个具有大截距$Δ_{\pom}$ = 0.23和斜率$α_{\pom}'$ = 0的Pomeron,因此提供了与微扰QCD的自然匹配。我们分析了弹性,单衍射和双衍射振幅,并比较的GLM振幅的行为,其他参数化。我们总结了LHC能区软相互作用竞争模型的主要特点和结果。

英文摘要:

We describe the elements of the GLM model that successfully describes soft hadronic interactions at energies from ISR to LHC. This model is based on a single Pomeron with a large intercept $Δ_{\pom}$ = 0.23 and slope $α_{\pom}'$ = 0, and so provides a natural matching with perturbative QCD. We analyze the elastic, single diffractive and double diffractive amplitudes, and compare the behaviour of the GLM amplitudes to those of other parameterizations. We summarize the main features and results of competing models for soft interactions at LHC energies.
