Cold kaons from hot fireballs

The E814 collaboration Has found a component of very low mt K+ mesons with a slope parameter of T ∼ 15 MeV. We will present a scenario which explains the observed slope parameter and which allowa us to predict the expected slope parameter for kaons produced in heavier systems such as Au+Au. Implications for the restoration of chiral symmetry in relativistic heavy ion collisions are discussed.
