Kaon and Lambda productions in relativistic heavy ion collisions

A microscopic approach has been employed to study the kaon and Λ productions in heavy ion collisions. The productions of K+ and Λ have been studied within the framework of Boltzmann transport equation for various beam energies. We find a non-monotonic horn like structure for K+/pi+ and Λ/π when plotted against centre of mass energies ( sNN ) with the assumption of initial partonic phase for sNN shows a monotonic nature when a hadronic initial state is considered for all sNN . Experimental values of K−/π− for different sNN are also reproduced within the ambit of the same formalism.
