Аннотация:HYDJET++ is a Monte-Carlo event generator for the simulation of relativistic heavy ion AA collisions considered as a superposition of the soft, hydro-type state and the hard, multi-parton state. This model is the development and continuation of HYDJET event generator (Lokhtin & Snigirev, 2006, EPJC, 45, 211). The main program is written in the object-oriented C++ language under the ROOT environment. The hard part of HYDJET++ is identical to the hard part of Fortran-written HYDJET and is included in the generator structure as a separate directory. The soft part of HYDJET++ event is the 'thermal' hadronic state generated on the chemical and thermal freeze-out hypersurfaces represented by the parameterization of relativistic hydrodynamics with preset freeze-out conditions. It includes longitudinal, radial and elliptic flow effects and decays of hadronic resonances. The corresponding fast Monte-Carlo simulation procedure, C++ code FAST MC (Amelin et al., 2006, PRC, 74, 064901/ 2008, PRC, 77, 014903) is adapted to HYDJET++. It is designed for studying of multi particle production in the wide energy range of heavy ion experimental facilities: from FAIR and NICA to RHIC and LHC.
