@article{10272/18566, year = {2014}, month = {5}, url = {http://hdl.handle.net/10272/18566}, abstract = {Gluon and ghost propagators data, obtained in Landau gauge from lattice simulations with two light and two heavy dynamical quark flavours (Nf=2+1+1), are described here with a running formula including a four-loop perturbative expression and a nonperturbative OPE correction dom- inated by the local operator A2. The Wilson coefficients and their variation as a function of the coupling constant are extracted from the numerical data and compared with the theoretical ex- pressions that, after being properly renormalized, are known at O( 4). As also ms is rather well known for Nf=2+1+1, this allows for a precise consistency test of the OPE approach in the joint description of different observables.}, publisher = {American Physical Society}, title = {Testing the OPE Wilson coefficient for A2 from lattice QCD with a dynamical charm}, doi = {10.1103/PhysRevD.87.074033}, author = {Blossier, B. and Boucaud, Ph. and Brinet, M. and Rodríguez Quintero, José}, }
