S. V. Molodtsov, M. K. Volkov, G. M. Zinovjev

摘要:

在四费米子相互作用的拉氏量模型中研究了介子关联函数。我们证明了尽管系统的平均能量和相应的夸克凝聚的奇异性,介子观测量是有限的,相当好的识别和实验能量标度兼容。它允许人们用相似的模型哈密顿量来描述夸克/强子系统的非平衡特性,这些特性在研究超相对论性重离子碰撞中得到了揭示。给出了Keldysh模型中介子关联函数的解析结果。

英文摘要:

Meson correlation functions are studied in the model with four-fermion interaction Lagrangian. We demonstrate that despite the singular character of system mean energy and corresponding quark condensate found out the meson observables are finite, quite well identified and compatible with experimental energy scale. It allows one to use the similar model Hamiltonians for describing the nonequilibrium features of quark/hadron systems which reveal themselves in studying ultrarelativistic heavy ion collisions. The analytical results for meson correlation functions in the Keldysh model are given.
