关于高能QCD中Reggeon场的关联函数和Wilson线的算符

On correlators of Reggeon fields and operators of Wilson lines in high energy QCD

S. Bondarenko, S. Pozdnyakov

摘要:

本文在Lipatov的高能QCD有效作用量理论\cite{LipatovEff,Our1,Our2,Our3,Our4}的框架下,导出正则化胶子场关联函数的Dyson-Schwinger方程族.给出了包含四个Reggeon场的关联函数~相关器的显式微扰表达式,并讨论了两个Reggeon场相关器方程解的不同微扰格式。利用\cite{Our4}文献的结果建立了正则化胶子场的关联函数与纵向胶子场的Wilson线算符之间的对应关系。JIMWLK-Balitsky形式主义和Lipatov的有效作用量方法之间的联系和应用所获得的结果进行了讨论。

英文摘要:

In this note we derive Dyson-Schwinger hierarchy of the equations for the correlators of reggeized gluon fields in the framework of Lipatov's high energy QCD effective action formalism, \cite{LipatovEff,Our1,Our2,Our3,Our4}. The explicit perturbative expressions for the correlators till correlator of four Reggeon fields inclusively are obtained and different perturbative schemes for the solutions of the equation for the two-field correlator are discussed. A correspondence between the correlators of reggeized gluon fields and Wilson line operators of longitudinal gluon field is established with the help of \cite{Our4} paper results. The connection between the JIMWLK-Balitsky formalism and Lipatov's effective action approach and applications of the obtained results are also discussed.
