Collective flow of K^＋ mesons in heavy-ion collisions predicted by the covariant Kaon dynamics

The directed and elliptic flow of positively charged kaons produced in5828Ni+5828Ni reactions at incident kinetic energy 1.91 AGe V are studied within the covariant kaon dynamics and compared to new data. We observe that the influence of the Lorentz force on the directed and differential directed flow of K+mesons is obvious. Our calculated results indicate that it is necessary for the Lorentz force to be included in the kaon dynamics in order to reasonably describe experimental data.
