Systematic study of the kaon to pion multiplicity ratios in heavy-ion collisions
We present a systematic study of the kaon to pion multiplicity ratios ${(K}^{+}/{\ensuremath{\pi}}^{+}$ and ${K}^{\ensuremath{-}}/{\ensuremath{\pi}}^{\ensuremath{-}})$ in heavy-ion collisions from AGS to RHIC energy using the relativistic quantum molecular dynamics (RQMD) model. The model describes reasonably well the available experimental data on ${K}^{+}/{\ensuremath{\pi}}^{+}$ and ${K}^{\ensuremath{-}}/{\ensuremath{\pi}}^{\ensuremath{-}}.$ Within the model, we find that …
