Abstract: We have investigated the effect of noise and friction on domain formation in a disoriented chiral condensate. We solve the equation of motion of the linear sigma model, in the Hartree approximation, including a friction and a white noise term. For a quenched initial condition, we find that even in the presence of noise and dissipation a domain-like structure emerges after a few fermi of evolution. Domain sizes as large as 5 fm can be formed.
