RT Journal Article T1 Vacuum expectation value of A2 from LQCD. A1 Pène, O. A1 Blossier, Benoit A1 Boucaud, Ph. A1 Rodríguez Quintero, José AB We argue from LQCD that there is a non vanishing v.e.v of Aμa Aaμ in QCD in the Landau gauge.We use operator product expansion to provide a clear definition of Aμa Aaμ and extract a numberboth in the quenched and unquenched case.
