Strangeness enhancement in the String Fusion Model Code

String Fusion Model Code results for Pb–Pb central collisions at SPS energies including the string fusion interaction mechanism are compared to the last experimental data. Predictions for RHIC energies are also presented. On the other hand, the evolution of the strangeness enhancement ratio $E_s=\frac{<\mathrm{\Lambda }>+4<K_s^0>}{3<{\pi }^{-}>}$ with the energy and with the atomic number of participant nuclei is discussed.
