摘要： 我们通过计算从包含Gribov参数的Zwanziger局域可重正化拉格朗日得出的horizon条件的两圈修正，确定了Landau规范下量子色动力学在MSbar方案中Gribov的质量间隙方程的两圈修正。我们验证了利用显式结果，两圈鬼传播子在红外区域得到了增强。 显示英文摘要

摘要： We determine the two loop correction to Gribov's mass gap equation for quantum chromodynamics in the Landau gauge in the MSbar scheme by computing the two loop correction to the horizon condition derived from Zwanziger's local renormalizable Lagrangian which incorporates the Gribov parameter. We verify that with the explicit result, the two loop ghost propagator is enchanced in the infrared.
