2.4
A Monte-Carlo model of jet quenching in ultrarelativistic heavy ion collisions
|
HYDJET++ , event generator under the ROOT FRAMEWORK for simulation of relativistic heavy ion AA collisions as a superposition of the soft, hydro-type state and the hard, multi-parton state.
The main routine is written in the object-oriented C++ language under the ROOT environment. The hard, multi-partonic part of HYDJET++ event is identical to the hard part of Fortran-written HYDJET (PYTHIA6.4xx + PYQUEN1.5.x) and is included in the generator structure as the separate directory. The soft part of HYDJET++ event represents the thermal hadronic state obtained with the Bjorken-like parameterization of freeze-out hypersurface and includes longitudinal, radial and elliptic flow effects and decays of hadronic resonances. The corresponding fast Monte-Carlo simulation procedure (C++ code) FAST MC is adapted.
