Objective The purpose of the project is to obtain a quantitative understanding of the structure and properties of matter and of the forces that permanently bind quarks into hadrons. This will be achieved by developing the lattice formulation of Quantum Chromodynamics (QCD), exploiting it in large-scale simulations and combining the results with experimental data. The project aims to continue already existing collaboration between participants from NIS and INTAS countries as well as to establish new links. A special effort will be made to provide young NIS scientists with opportunity of training in the field of computational physics.The specific goals of the project include:-evaluation of the non-perturbative QCD effects, for the first time with dynamical fermions included, for a wide variety of physical processes which will lead to a precise determination of the parameters of the Standard Model, thus subjecting it to rigorous quantitative tests;-investigation of the non-perturbative structure of the vacuum with the aim to perform a detailed study of the dynamical and static properties of monopoles, vortices and instantons in terms of the dependence on the sea quark mass;-development of algorithms for the efficient generation of gauge field configurations with improved actions and including sea quarks; development and test of the lattice QCD actions with superior chiral properties in order to allow physical light quarks to be simulated.The research program is based on the combination of computer simulations and analytical calculations.The following results are to be obtained at the end of the project:-precise computation of the hadron spectrum, including eta_prime mass, and of the light quark masses in full lattice QCD with the error below 10%;-first computation of the nucleon structure functions (polarized and unpolarized) with dynamical quarks;-precise computation of the weak matrix elements with the use of new techniques of nonperturbative renormalization developed within the scope of this project;-nonperurbative test of the Operator Product Expansion; -first check of the validity of the dual superconducting model for the vacuum of QCD with dynamical quarks effects included will be completed;-the effective potential for monopoles will be calculated and the interrelation of monopoles, centre vortices and instantons will be established in lattice QCD with dynamical quarks;-practical implementation of the recent proposals for fermion actions with improved chiral properties (perfect action, overlap action, Slavnov's action) as well as of the effective numerical algorithms to simulate lattice quarks with light physical masses (Multi Boson, Noisy Monte-Carlo).
