Abstract
This is the second of two papers on a continuum version of the Potts model, where particles are points in , , with a spin which may take possible values. Particles with different spins repel each other via a Kac pair potential of range , . In this paper we prove phase transition, namely we prove that if the scaling parameter of the Kac potential is suitably small, given any temperature there is a value of the chemical potential such that at the given temperature and chemical potential there exist mutually distinct DLR measures.
