Abstract
In a series of papers we have developed a Monte Carlo model based on Mueller’s dipole picture of BFKLevolution supplemented with nonleading corrections which has shown to be very successful in describing inclusive and semiinclusive observables in hadron collisions In this paper we present a further extension of this model to also describe exclusive final states This is a highly nontrivial extension and we have encountered many details that influence the description and for which no guidance from perturbative QCD could be found Hence we have had to make many choices based on semiclassical and phenomenological argumentsThe end result is a new event generator called dipsy which can be used to simulate complete minimumbias nondiffractive hadronic collision events Although the description ofdata from the Tevatron and LHC is not quite as good as for Pythia 8 the most advanced of the general purpose event generator programs for these processes our results are clearly competitive and can be expected to improve with careful tuning In addition as our model is very different from conventional multiple scattering scenaria the dipsy program can be used to gain deeper insight in the soft and semihard processes involved both in hadronic and heavy ion collisionsThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
