Analysis of the (i) charge balance function and (ii) fluctuations net electric hadrons in Pb+Pb collisions at center-of-mass energy 2.76 TeV per nucleon pair was performed within a two-component hydjet++ model. It is shown that neither widths nor strongly intensive quantities, D Σ, used to describe net-charge fluctuations, can be reproduced model based on grand canonical ensemble approach for generating multiparticle production. To solve this problem, it necessary take into account exact...

Partial contributions of elliptic v_2 and triangular v_3 flows to the hexagonal v_6 flow are studied within HYDJET++ model for Pb+Pb collisions at sqrt{s}=2.76 TeV. Scaling ratio v_6^{1/6}{Psi_2} / v_2^{1/2}{Psi_2} in plane, Psi_2, is predicted range 1 < p_T 4 GeV/c semicentral semiperipheral collisions. Jets increase this by about 10% also cause its rise > 3.5 GeV/c. The part coming from instantly increasing as reaction becomes more peripheral, whereas contribution drops. This behavior...

The Monte Carlo HYDJET++ model, that contains both hydrodynamic state and jets, is applied to study the influence of interplay between soft hard processes on formation elliptic flow in heavy-ion collisions at RHIC LHC energies. Jets are found cease hydro-like increase with rising p_T. Since jets more influential than RHIC, v_2 should be weaker RHIC.

The data on charge balance function in Pb+Pb collisions at center-of-mass energy 2.76 TeV per nucleon pair are analyzed with the HYDJET++ model. For central collisions, width of low transverse momentum intervals is larger model than data. An approach, which takes into account event-by-event conservation, has been implemented thermal part stage hadron production. This approach implies two particle correlations a certain length and allows to reproduce experimental widths.

Fluctuations of anisotropic flow in lead-lead collisions at LHC energies arising HYDJET++model are studied. It is shown that intrinsic fluctuations the which appear mainly because particle multiplicity, momenta and coordinates insufficient to match measured experimental data, provided eccentricity freeze-out hypersurface fixed any given impact parameter b. However, when variations HYDJET++ taken into account, agreement between model results data drastically improved. Both calculations...

Abstract It has been dozen years since HYDJET++ Monte-Carlo event generator for the simulation of relativistic heavy ion collisions was developed. Now is widely used nucleus-nucleus interactions from NICA to LHC energies. The model calculations on soft and hard probes quark-gluon plasma (including collective flow, different kinds particle correlations, jets, D B mesons etc.) agree well with experimental data. In this paper selected main results very new ones are presented.
