“…-Charged particle multiplicity: in this case (Fig. 28) a very good agreement between the theoretical predictions of the Charged particle number probability distribution: comparison among SHM predictions, Herwig6510 predictions and OPAL data [25] SHM and the experimental data is present. It is worth noting that for this distribution, in particular for the distribution tails, the predictions of the SHM show a better agreement with the experimental data with respect to Herwig6510's results.…”

We present a Monte-Carlo implementation of the Statistical Hadronization Model in e + e − collisions. The physical scheme is based on the statistical hadronization of massive clusters produced by the event generator Herwig within the microcanonical ensemble. We present a preliminary comparison of several observables with measurements in e + e − collisions at the Z peak. Although a fine tuning of the model parameters is not carried out, a general good agreement between its predictions and data is found.

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.
