Pomeron增强的现象学

The Phenomenology of Pomeron Enhancement

E. Gotsman, E. Levin, U. Maor, J. S. Miller

摘要:

多重坡密子相互作用是高质量衍射的主要来源。它们在高能动力学中的作用极大地影响了硬衍射通道的高能截面和生存概率的预测,特别是在LHC的衍射希格斯生产。我们的方法,是出于这样一个事实,即我们得到一个非常小的值的坡密子轨迹,这证明了使用微扰QCD软散射的拟合斜率。我们建议的模型不同于达勒姆KMR组的建议,这是基于部分子模型解释的Reggeon演算在复杂的J-平面中,其中多个Pomeron顶点是任意定义的。两组的理论输入和预测,以及他们的数据分析和程序进行了比较和评价。

英文摘要:

Multi Pomeron interactions are the main source of high mass diffraction. Their role in high energy dynamics greatly influences the predictions for high energy cross sections and survival probabilities of hard diffraction channels, notably, diffractive Higgs production at the LHC. Our approach, is motivated by the fact that we obtain a very small value for the fitted slope of the Pomeron trajectory, which justifies the use of perturbative QCD for soft scattering. Our suggested model differs from the proposal of the Durham KMR group which is based on a parton model interpretation of the Reggeon calculus in the complex J-plane in which multi Pomeron vertices are arbitrarily defined. The theoretical input and predictions of the two groups, as well as their data analysis and procedures are compared and evaluated.
