Abstract：
The directed and elliptic flow of positively charged kaons produced in ₂₈ ⁵⁸Ni+ ₂₈ ⁵⁸Ni reactions at incident kinetic energy 1.91 AGeV 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.
