- * *
- * HYDJET++ , event generator under the ROOT FRAMEWORK for simulation of *
- * relativistic heavy ion AA collisions as the superposition of soft, *
- * hydro-type state and 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) 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 *
- * parameterization Bjorken-like 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. *
