The degrees of freedom observed in hadronic collisions at high energies can be  strongly entangled with the rest  degrees of freedom in the initial light cone hadronic wavefunction. The coherence of the incoming hadron is destroyed by the interaction with the target; this may lead to the transformation of   the entropy associated with the entanglement into the thermodynamics entropy of produced particles. We study the entanglement entropy at small x in the Color Glass Condensate effective field theory.   In particular, we compute the entanglement entropy of soft gluon field beyond the dilute approximation  in the MV model for the soft gluon fields. We  discuss the small x evolution of entanglement entropy described by the JIMWLK renormalization group equation.
