AI 中文摘要
非微扰规范理论的有效激发问题尚未完全明晰。本文以改进的Gribov-Zwanziger(RGZ)理论作为纯规范Yang-Mills理论的有效模型,重新研究该理论的准粒子(二次型)激发,结合RGZ拉格朗日量的显式PT对称性,针对实质量极点情况提出了这类准粒子的新诠释。
英文摘要
The problem of the effective excitations of a gauge theory in the nonperturbative regime remains not completely understood. Using the Refined Gribov-Zwanziger (RGZ) theory as effective model for pure gauge Yang-Mills theories, we revisit the quasiparticle (quadratic) excitations of the theory. A novel interpretation of such quasiparticles is proposed, in the case of real mass poles, taking into account the manifest ${\cal PT}-$symmetry of the RGZ Lagrangian.
