The Linked Dipole Chain Monte Carlo

Abstract

. We are working on a full-scale Monte Carlo simulation program [1] for describing e-p collisions. This MC is based on the Linked Dipole Chain (LDC) model which, in turn, is a modification and generalization of the CCFM model. Here I will start by explaining the basic model, then describe the MCimplementation and finish with some preliminary results. INTRODUCTION Generally in perturbative e-p DIS models one assumes that a parton is picked up from a proton parton distribution at low virtuality. After some perturbative emissions, called Initial State Bremsstrahlung (ISB), one ends up with a quark which interacts with the electron. More partons are then emitted from the initial ladder and those are called Final State Bremsstrahlung (FSB). In a realistic model one must also include a hadronization process where the partons become jets of colour singlet hadrons. With the Linked Dipole Chain (LDC) model [2], one can perform both the ISB, to evaluate the structure function or the cross secti..
