We study an infinite system of Brownian hard balls,
moving in R^d and submitted to a smooth infinite range
pair potential. It is represented by a diffusion process,
which is constructed as the unique strong solution of an
infinite dimensional Skorohod equation. We also prove that
canonical Gibbs states associated to the sum of the hard
core potential and the pair potential are reversible measures for the dynamics.
