Abstract
Intensive numerical studies of exact ground states of the 2-d ferromagnetic random field Ising model at T=0 with gaussian distribution of fields are presented. Standard finite size scaling analysis of the data suggests the existence of a transition at sigma_c= 0.64 +/- 0.08. Results are compared with existing theories and with the study of metastable avalanches in the same model.
