Abstract: A new mechanism is proposed for interpretation of the non-monotonic, enhanced yield of hyperons and positive strange mesons (also known as “horn” effect) that was observed in central heavy ion collisions in the experiment NA49 at SPS. We argue that the data indicate the transition of the nucleons in the overlap region of colliding nuclei with high nuclear density into a certain hyperon phase. This nucleon-to-hyperon transition is accompanied by enhanced yields of positive kaons. The “horn”-effect is a consequence of an interplay between the energy/baryon density attained in the overlap region of colliding nuclei and the overlap time.
