The event generator DPMJET-III at cosmic ray energies

The Monte Carlo Event Generator DPMJET-III

A new version of the Monte Carlo event generator Dpmjet is presented. It is a code system based on the Dual Parton Model and unifies all features of the Dtunuc-2, Dpmjet-II and Phojet1.12 event generators. Dpmjet-III allows the simulation of hadron-hadron, hadron-nucleus, nucleus-nucleus, photon-hadron, photonphoton and photon-nucleus interactions from a few GeV up to the highest cosmic ray ene...

Rhic Data and the Multichain Monte Carlo Dpmjet-iii *

Using data from RHIC we are able to systematically improve the two-component Dual Parton Model (DPM) event generator DPMJET-III. Introducing percolation parametrized as fusion of chains the model describes mul-tiplicities and pseudorapidity distributions in nucleus-nucleus collisions at all centralities. Guided by the d-Au data from RHIC we recalibrate the model to obtain collision scaling in h...

0 Baryon stopping in high energy collisions in the DPMJET – III model

A recently discovered feature of hadron production in nuclear collisions is the large stopping of the participating nucleons in hadron–nucleus and nucleus– nucleus collisions. Experimental data demonstrating this effect have been presented in [1,2]. Multistring fragmentation models like the Dual Parton Model (DPM) or similar models did originally not show this enhanced stopping in nuclear colli...

d–Au and p–p collisions at RHIC and the multichain Monte Carlo Dpmjet-III ∗

In this paper we compare systematically the two-component Dual Parton Model (DPM) event generator Dpm-jet-III to d-Au and p–p data from RHIC. In this process we are able to improve the model. The need for fusion of chains and a recalibration of the model to obtain collision scaling in h-A and d-A collisions was found already in previous comparisons. Here, comparing to transverse momentum distri...
