Pomeron模型中的PT对称性和重整化

PT Symmetry and Renormalization in a Pomeron Model

G. P. Vacca

摘要:

本文对pomeron的2+1局域超临界场论进行了新的微扰分析。它是基于PT对称性的模型,它允许研究一个类似的哈密顿与相同的真正的微扰谱。在最低的非平凡阶微扰理论的坡密子相互作用,导致重整化的斜率。两个坡密子态的非定域相互作用的出现是这样的,在小耦合下,仅存在散射态,而两个粒子态的光谱不受影响。

英文摘要:

A novel perturbative analysis for the 2+1 local supercritical field theory of pomerons is developed. It is based on the PT symmetry of the model which allows to study a similar Hamiltonian with the same real perturbative spectrum. In the lowest non trivial order of perturbation theory the pomeron interactions are shown to lead to the renormalization of the slope. The appearance of a non local interaction for two pomeron states is such that at small coupling only scattering states are present and the spectrum of two particle states is not affected.
