Vacuum expectation value of A^2 from LQCD

High Energy Physics - Lattice 2015-03-18 v1

Abstract

We argue from LQCD that there is a non vanishing v.e.v of AaμAμaA_a^\mu A^a_\mu in QCD in the Landau gauge. We use operator product expansion to provide a clear definition of AaμAμaA_a^\mu A^a_\mu and extract a number both in the quenched and unquenched case.
