Enhancement of low-$m_t$ kaons in AGS heavy-ion collisions

Abstract

In the relativistic transport model, we show that the recently observed enhancement of low-$m_t$ kaons ($K^{+}$ and $K^{-}$) in Si+Pb collisions at AGS can be explained if a density isomer is introduced in the nuclear equation-of-state.
