The yields of strange particles are calculated with the ultrarelativistic quantum molecular dynamics model for p, Pb(158 A GeV)Pb collisions and compared with experimental data. The yields are enhanced in central collisions compared with proton-induced or peripheral Pb + Pb collisions. The enhancement is due to secondary interactions. Nevertheless, only a reduction of the quark masses or equivalently an increase of the string tension provides an adequate description of the large observed enhancement factors (WA97 and NA49). Furthermore, the yields of unstable strange resonances such as the A* or the φ are considerably affected by hadronic rescattering of the decay products.
