Cold Kaons from hot fireballs

Abstract

The E814-collaboration has found a component of very low $m_t$ $K^{+}$ mesons with a slope parameter of $T\sim 15\mathrm{MeV}$. We will present a scenario which explains the observed slope parameter and which allows us to predict the expected slope parameter for kaons produced in heavier systems such as Au+Au. We also will discuss the effect of the coulomb interaction on the structure of the spectrum.
