“…For historical reasons, we also briefly mention an alternative underlying event model available in Herwig++: the UA5 model [67], even though this is ruled out by data and not recommended for serious use. Finally we will describe the code structure, which implements these ideas.…”

In this paper we describe Herwig++ version 2.2, a general-purpose Monte Carlo event generator for the simulation of hard lepton-lepton and hadron-hadron collisions. A number of important hard scattering processes are available, together with an interface via the Les Houches Accord to specialized matrix element generators for additional processes. The simulation of Beyond the Standard Model (BSM) physics includes a range of models and allows new models to be added by encoding the Feynman rules of the model. The parton-shower approach is used to simulate initial-and final-state QCD radiation, including colour coherence effects, with special emphasis on the correct description of radiation from heavy particles. The underlying event is simulated using an eikonal multiple parton-parton scattering model. The formation of hadrons from the quarks and gluons produced in the parton shower is described using the cluster hadronization model. Hadron decays are simulated using matrix elements, where possible including spin correlations and off-shell effects.

“…If the option of using the soft underlying event model [67] is used, as described in Sect. 8.3, then the UnderlyingEventHandler needs to be set to theUA5Handler, by default this is set to the NULL pointer and the multiple scattering model of the underlying event described in Sect.…”

Abstract. Proton-proton collisions at energies from √ s = 200 GeV up to √ s = 14 TeV are studied within the microscopic quark-gluon string model. The model is based on Gribov's Reggeon Field Theory accomplished by string phenomenology. Comparison with experimental data shows that QGSM describes well particle yields, rapidity-and transverse momentum spectra, rise of mean �p T � and forward-backward multiplicity correlations. The latter arise in QGSM because of the addition of various processes with different mean multiplicities. The model also indicates fulfillment of extended longitudinal scaling and violation of Koba-Nielsen-Olesen scaling at LHC. The origin of both features is traced to short-range particle correlations in the strings. Predictions are made for √ s = 14 TeV.

Abstract. The microscopic Monte Carlo quark-gluon string model (QGSM) is employed to study particle production in ultrarelativistic proton-proton collisions. The model is based on Reggeon Field theory accomplished by string phenomenology. Various observables, including multiplicity, rapidity and transverse momentum spectra, short-range, long-range and femtoscopy correlations, are described quite well in a wide span of the collision energy. Predictions are made for pp collisions at √ s = 14 TeV.
