Bose-Einstein correlations of pion pairs and kaon pairs from relativistic quantum molecular dynamics

Bose-Einstein correlations between charged pion and ${\mathit{K}}^{+}$ pairs are calculated using the space-time and four-momentum distributions from relativistic quantum molecular dynamics for 200 GeV/nucleon ${}_{}{}^{32}{}_{}{}^{}$S+Pb and compared to pion correlation measurements from two CERN experiments. Good agreement is found. The predicted apparent radii from the ${\mathit{K}}^{+}$ correlation functions are smaller than the corresponding pion radii.
