TY - JOUR ID - citeulike:6012584 L3 - citeulike-article-id:6012584 N2 - A system is in a self-organized critical state if the distribution of some measured events obeys a power law. The finite-size scaling of this distribution with the lattice size is usually enough to assume that the system displays self-organized criticality. This approach; however; can be misleading. In this paper we analyze the behavior of the branching rate σ of the events to establish whether a system is in a critical state. We apply this method to the Olami-Feder-Christensen model to obtain evidence that; in contrast to previous results; the model is critical in the conservative regime only.
