英文摘要: The K+ production and flow in relativistic heavy-ion collisions are investigated with the self-consistent relativistic Boltzmann-Uehling-Uhlenbeck (RBUU) approach. The results show that the kaon flow is sensitive to both the kaonnucleon sigma term Sigma(KN) and the equation of state (EOS) of nuclear matter. We find that anti-flow appears at certain large impact parameter, which can provide more definite information of the magnitude of Sigma(KN). We have also analyzed the dependence of the total K+ production probability and the contributions from different channels on the EOS and the Sigma(KN). The sensitivity to the nuclear equation of the state and Sigma(KN) is different for different channels. Overall, the contribution from N Delta channel is the most important.
