Improvement of DPM Generator

This study presents improvements in Dual Parton Model (DPM) generator focusing on hadron scattering. The results of DPM on inelastic pbar-p interactions in PandaRoot are discussed, alongside the tunning of quark-gluon string model. New parameters are introduced for hadron elastic scattering to enhance the simulation accuracy. Notable additions include the inclusion of string junction annihilation and quark-antiquark annihilation subprocesses. The implementation of Low Mass Diffraction helps enhance the spectra of protons and antiprotons. The study also covers the effects of Coulomb, interference, and hadron parts in elastic scattering within the DPM generator. Key improvements include the fixed status of DPM, enhanced meson spectra, and improved parametrization of hadron elastic scattering. Overall, these advancements aim to provide a more accurate representation of hadron interactions within the DPM framework.
