The photon transverse momentum spectrum and its anisotropy from Pb+Pb collisions at the CERN Large Hadron Collider energy √ s NN = 2.76 TeV are investigated within the integrated hydrokinetic model (iHKM). Photon production is accumulated from the different processes at the various stages of relativistic heavy ion collisions: from the primary hard photons of very early stage of parton collisions to the thermal photons from equilibrated quark-gluon and hadron gas stages. Along the way a hadronic medium evolution is treated in two distinct, in a sense opposite, approaches: chemically equilibrated and chemically frozen system expansion. Studying the centrality dependence of the results obtained allows us to conclude that a relatively strong transverse momentum anisotropy of thermal radiation is suppressed by prompt photon emission which is an isotropic. We find out that this effect is getting stronger as centrality increases because of the simultaneous increase in the relative contribution of prompt photons in the soft part of the spectra. The substantial results obtained in iHKM with nonzero viscosity (η/s = 0.08) for photon spectra and v 2 coefficients are mostly within the error bars of experimental data, but there is some systematic underestimation of both observables for the near central events. We claim that a situation could be significantly improved if an additional photon radiation that accompanies the presence of a deconfined environment is included. Since a matter of a space-time layer where hadronization takes place is actively involved in anisotropic transverse flow, both positive contributions to the spectra and v 2 are considerable, albeit such an argument needs further research and elaboration.

Abstract. Geometrical properties of nucleus-nucleus interactions at various centralities are calculated for the NICA energy range. A modified version of the Glauber Monte Carlo simulation code has been used for the calculations. It is shown that the geometrical properties of nucleus-nucleus interactions at the energies 5 -10 GeV (NICA/MPD) and at energy 200 GeV (RHIC) are quite close to each other. A possible determination of centrality at NICA/MPD experiment using calculations of various Monte Carlo event generators are considered.

During the last two to three years extensive development of the Geant4 simulation toolkit has occurred, which will culminate in a major release at the end of 2013. This development includes the adoption of multi-threading, the extension and improvement of physics models, improvements to the geometry modeler with a revised implementation of most geometrical primitives, advances in visualization and graphical user interfaces (GUI), the move from GNU make to CMake and the extension and automation of the Geant4 testing suite. The reasons for and implementation of multi-threading will be discussed. Certain electromagnetic and hadronic model extensions will also be discussed along with their effects on calorimeter results. Finally, visualization and GUI improvements will be highlighted along with the new configuration, build and testing systems.
