Mott-Anderson freeze-out and the strange matter "horn"
We discuss the $\sqrt{s}$-dependence of the $K^+/\pi^+$ ratio in heavy-ion collisions (the "horn" effect) within a Mott-Anderson localization model for chemical freeze-out. The different response of pion and kaon radii to the hot and dense hadronic medium results in different freeze-out co...
