Investigation of hot and compressed matter, in particular strangeness production in nucleus-nucleus collision Flow intensity in HI collisions Reinhard Kulessa
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 exchange reactions, and reduction of K- effective mass in dense nuclear matter AND Reinhard Kulessa
