Reinhard Kulessa19 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
