局域超临界Pomeron模型中的PT对称性和Hermithean哈密顿量

PT Symmetry and Hermithean Hamiltonian in the Local Supercritical Pomeron Model

M. A. Braun, G. P. Vacca

摘要:

利用哈密顿量表述中的PT对称性,微扰地研究了局域场场论。在最低的非平凡的顺序,我们表明,坡密子相互作用重整化的斜率。在相同的顺序下,我们发现了一个非定域的对势作用在pomeron之间,它具有奇异的结构。但对散射算符的分析表明,在小的耦合常数下,束缚态不出现,因而两粒子能谱不发生变化。

英文摘要:

The local reggeon field theory is studied perturbatively taking advantage of the PT symmetry in the Hamiltonian formulation. In the lowest non trivial order we show that the pomeron interactions renormalize the slope. In the same order we find a non local pair potential acting between pomerons, which has a singular structure. However the analysis of the scattering operator shows that at small coupling constant bound states do not appear so that the two-particle spectrum is not changed.
