Objective
PROJECT SUMMARY We summarize the objectives, a short description of the research activities and expected results of the Project: 1. Analytical calculation of four and five-loop contributions to the muon (g-2)/2 factor and improvement of the numerical algorithms for these calculations 2. New calculation of the leading order hadronic contribution to the value of muon (g-2)/2 using the dressed hadronic cross sections of e+e- annihilation. 3. Development of the new approaches to the calculation of the light-by-light hadronic contribution to the value of muon (g-2)/2. 4. Accurate calculation of the vacuum polarization function based on the full experimental data sets. 5. Calculation of the radiative corrections with per mille accuracy to the cross section of the Bhabha scattering at large angles and for the main hadronic channels. 6. Experimental study of the final state radiation effects in the processes e+e- -> pi+pi-gamma and e+e- -> mu+mu-gamma based on the CMD-2 detector data. 7. Development of the Monte Carlo codes with per mille accuracy for the large angle Bhabha scattering as well as for the processes e+e- -> pi+pi-gamma, e+e- -> mu+mu-gamma and e+e- -> gammagamma. 8. Development of the Monte Carlo codes for multihadronic processes taking into account final state radiation effects. 9. High precision calculation and development of the corresponding Monte Carlo codes for the radiative return processes. 10. Development and implementation of the common libraries of formfactors for low energy e+e- processes.
