格点量子色动力学中胶子和鬼传播子的红外指数

Infrared exponents of gluon and ghost propagators from Lattice QCD

O. Oliveira, P. J. Silva

摘要:

讨论了量子色动力学Dyson-Schwinger方程(DSE)的纯幂律红外解与朗道规范中胶子和鬼传播子的格点数据的相容性。对于胶子传播子,晶格数据与具有指数$κ\sim0.53$的DSE红外解兼容,该指数是使用抑制有限体积效应的技术测量的,并且允许对晶格数据的这些校正进行建模。对于鬼传播子,晶格数据似乎不遵循红外DSE幂律解。

英文摘要:

The compatibility of the pure power law infrared solution of QCD Dyson-Schwinger equations (DSE) and lattice data for the gluon and ghost propagators in Landau gauge is discussed. For the gluon propagator, the lattice data is compatible with the DSE infrared solution with an exponent $κ\sim0.53$, measured using a technique that suppresses finite volume effects and allows to model these corrections to the lattice data. For the ghost propagator, the lattice data does not seem to follow the infrared DSE power law solution.
