A modification of Faddeev-Popov approach free from Gribov ambiguity
Chong-yao Chen, Fei Gao, Yu-xin Liu
We propose a modified version of the Faddeev-Popov quantization approach for non-Abelian gauge field theory to avoid the Gribov ambiguity. We show that by means of introducing a ne…
A Universal Constraint on the Infrared Behavior of the Ghost Propagator in QCD
Fei Gao, Can Tang, Yu-xin Liu
With proposing a unified description of the fields variation at the level of generating functional, we obtain a new identity for the quark-gluon interaction vertex based on gauge s…
Locating the Gribov horizon
Fei Gao, Si-Xue Qin, Craig D. Roberts +1
We explore whether a tree-level expression for the gluon two-point function, supposed to express effects of an horizon term introduced to eliminate the Gribov ambiguity, is consist…
Exposing strangeness: projections for kaon electromagnetic form factors
Fei Gao, Lei Chang, Yu-Xin Liu +2
A continuum approach to the kaon and pion bound-state problems is used to reveal their electromagnetic structure. For both systems, when used with parton distribution amplitudes ap…
Temperature Effect on Shear and Bulk Viscosities of QCD Matter
Fei Gao, Yu-xin Liu
We investigate the temperature dependence of the shear and bulk viscosities and their ratios to the entropy density via a continuum QCD approach. We calculate the pion mass and dec…
