## SCL Seminar by Marina Krstic Marinkovic

Scientific Computing Laboratory seminar will be held on Monday, 13 June 2016 at 14:00 in the library reading room “Dr. Dragan Popović" of the Institute of Physics Belgrade. The talk entitled

will be given by Dr. Marina Krstić Marinković (Theoretical Physics Department, CERN).

Anomalous magnetic moment of the muon (a_mu) is one of the most precisely measured quantities in particle physics and it provides a stringent test of the standard model. With the planned improvement of the experimental precision at Fermilab and at J-PARC, further reduction of the theoretical uncertainty is required, in order to be able to resolve the current discrepancy between the experimental measurement of a_mu and its theoretical prediction, and potentially gain insight into new physics. The dominant source of the uncertainty in the theoretical prediction of a_mu are the errors of the hadronic contributions. In this talk we will explain several promising approaches for a precise determination of the leading hadronic contribution to a_mu. Finally, we will discuss the relevance of a precise estimate of the size of the isospin breaking effects for obtaining this quantity from lattice QCD simulations with sub-percent precision.
