There is considerable recent interest in exact solutions for models in the universality class of the 1D stochastic growth Kardar-Parisi-Zhang equation (KPZ). A prominent example of models believed to be in this universality class are directed polymers in random medium. In this talk I will show how one can classify the models of directed polymers on the square lattice which are integrable using the coordinate Bethe Ansatz. I will then present the detailed solution of one of this model and show its belonging to the KPZ universality class.
