Show affiliationsA mean-field approximation for a 1D non-equilibrium lattice model, known as model A, is considered allowing the authors to compute the probability of a configuration of a given cluster of sites. The mean-field equations are numerically solved in the stationary regime for different cluster sizes L (<or=15). From a finite-size analysis and the application of the coherent anomaly method (CAM) they compute the critical parameter of the model, the correlation length critical exponent nu perpendicular to and the order parameter critical exponent beta ; the results are in agreement with those obtained by other methods.
