Vacuum expectation value of A2 from LQCD. Proceedings of Science, The many faces of QCD Conference, 2010, p. 010.1824-8039http://hdl.handle.net/10272/18770We argue from LQCD that there is a non vanishing v.e.v of A μ a Aa μ in QCD in the Landau gauge. We use operator product expansion to provide a clear definition of A μ a Aa μ and extract a number both in the quenched and unquenched case.engAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/Vacuum expectationLQCDLandau gaugejournal articleopen access
