Kaon production in heavy ion collisions

Abstract

Intermediate and high energy heavy ion collisions provide a unique opportunity to investigate the properties of hadrons in dense nuclear matter. In particular, strange mesons are considered to be sensitive to in-medium modifications. Theory predicts a repulsive K+N potential in dense matter. We study the calculation production cross sections of K+mesons in heavy ion collisions at incident energy 1-2 A GeV for  collision and  collisions  within the quantum molecular dynamics (QMD) model. We also find that our calculated production cross sections of K+ mesons in A+A collisions by using the in-medium kaon potential and with soft EOS and hard EOS are in good agreement which KaoS data
