The main goals of the study of heavy ion collisions are to look for a phase transition between ordinary hadronic matter and quark-gluon plasma and to investigate its properties. Mach attention is paid to hard probes, which carry information about the early studies of the hot strong interacting matter evolution. In particular, the problem related to the production of jets and leading high-ð_| particles in dense matter, focusing on the LHC heavy ion program, will be investigated. The effects expected as a result of hard parton jet passing through QCD matter will be analyzed. The medium parameters, which primarily influence on the change in jet characteristics, and the possibility of their experimental observation will be studied under CMS condition.

Quantum chromodynamics (QCD), the gauge field theory that describes the interaction of coloured quarks and gluons, is one of the component of the SU(3)xSU(2)xSU(1) Standard Model. At short distances, equivalently high energies, the effective coupliny is small and the theory can be studied using perturbative techniques. Nowadays detailed tests of perturbative QCD are performed at all the high-energy colliders and in the production and decay of heavy quark systems. Another fundamental QCD process is the production of hadrons in electron-positron annihilation. The importance of this process in that it allows a detailed study of how quarks “shower” into multiparton states and how these materialize into jets of hudrons. These and other hard processes are planned to study in the framework of perturbative QCD.

The term of training - 1-2 years.

The analysis of EAS experimental data unavoidably demands to perform calculations which make it necessary to employ hadronic interaction models at energies exceeding limits within which models in question may be considered as experimentally established. The first aim to achieve is to find such approaches that could ensure the minimal model ependence of comclusions derived from EAS data end concerning primary cosmic ray energy spectrum and mass composition. At the same time it is of great importance to look for experimental EAS characteristics that would be sensitive to certain model parameters (for example, to inelastic cross sections of primaries). Such characteristics can be used to precise model parameters at energies well above those attained by modern colliders.

The term of training - 1-2 years.

Subject 9. Temporal, spectral and polarization parameters of solar flares hard electromagnetic radiation and dynamics of magnetosphere energetic electron fluxes at different phases of solar activity cycle

It is supposed to study during the post-doc duty the electron acceleration in the such active processes in the solar atmosphere as a nontermal processes during the pulse phase of a flare, coronal mass ejections, coronal shocks and other forms of energy release and their connection with hard X-ray burst generation. It is also supposed to study the properties of fluxes of electrons with energy abour dozens - hundreds keV in the inner Earth magnetosphere and their connection with solar activity. Simultaneously the problem of the solar cosmic ray flare energetic electron sources in the interplanetary space will be studied. The main attention will be pay to the unstudied electron fluxes near the geomagnetic equator.

It is also supposed that the post-doc duty will be based on the analysis of experimental data about active processes on the Sun and the quasy-trapped electron fluxes in the inner magnetosphere, which were obtained in several experiments from 1994 till now. By this it is planning to use first of all the data from the instruments operating on the Koronas-F orbital observatory (experiment was begun in August, 2001) as well as the data of well completed experiments on-board Koronas-I satellite (1994) and “Mir” orbital station (1005-1997). During the work it is planning to elaborate computer programs intended for Koronas-F observatory instruments data processing, to classify the X-ray bursts and to identify them with flares and other active processes on the Sun, to chose the solar cosmic ray events and to determine their parameters, to identify the solar cosmic ray events with X-ray bursts detected on the Koronas-F observatory as well as with coronal and interplanetary shocks, to evaluate the spectra and fluxes of energetic electrons inth solar atmosphere, to elaborate the data base of Koronas-F , to obtain the statistical dependence of the solar cosmic ray events paramenters on the flare and coronal mass ejection parameters, to study the separate solar cosmic ray events. For the complex and detailed analysis it is also planning to use the data about the condidtiond on the Sun and in the magnetosphere available in the Internet, in particular data of such experiments as SOHO, HESSI, GOES. The available data obtained for the large time interval from minimum to maximum of solar activity as well as the detection on the Koronas-F satellite of more than a dozens of solar flares for a recent year make it possible to evaluate experimentally the influence of different solar processes on the qyasy-trapped eelectron fluxes in the inner magnetosphere

The proposed program will include both theoretical studies and numerical simulations using a powerful computer complex.

A further investigation is proposed - a continuation of those being accomplished on the lines of a number of Russian and international projects. They relate to effects generated by action of powerful time-dependent processes characteristic for magnetospheric substorm. Their critical constituent is the dynamics of the current sheet in the geomagnetic tail.

The main goal is to obtain a detailed insight into the role of the current sheet evolution, both in the nonlinear process of breakdown of the initial magnetospheric equilibrium, and on the following stage of the system global evolution; to identify those various nonlinear dissipative structures which can arise at various conditions in the interplanetary space; to identify the effects of particle acceleration and transport and other significant for the “space weather” effects which can be a consequence.

The tenure will be performed at the base of the Skobeltsyn Institute of Nuclear Physics, Moscow State University, at the Department of Radiation and Computational Methods in the co-operation with the scientists from the Russian Academy of Sciences and in the collaboration with foreign partners.

The tenure terms are from 6 to 12 months according to the preference

The Program includes two blocks: theoretical studies and/or the work with the large data base of solar and heliospheric parameters for the investigation of the causes of strong geomagnetic perturbations. The Program is flexible and could be negotiated and modified according to the scientific interests of the potential candidate.

The theoretical bloc is oriented on the development of the MHD and kinetic models of the plasma and electrodynamic processes in the solar corona and the interplanetary space based on the analytical and numerical approaches.

The work with the data base (http://alpha.sinp.msu.ru/apev) assumes its further development and the use for the interpretation of the individual events in the chain of the solar-terrestrial relations during the current 23-rd solar cycle with the aim of the establishment of new general and specific characteristics which could be adapted for the implementation of the refined methods in the space weather evaluation and forecasts.
