Investigation of hot and compressed matter, in particular strangeness production in nucleus-nucleus collisionFlow intensity in HI collisions
24.11.2003 Reinhard Kulessa 19
In-medium modyfications of kaons and antikaons The properties of kaons and antikaons are modified in dense baryonic matter. In mean-field calculations, this effect is caused by repulsive K+N potential and attractive K-N potential. K- yield enhancement is explained by strangeness exchangereactions, and reduction of K- effective mass in dense nuclear matter
