Title Progress on the nucleon EDM calculations in lattice QCD
Abstract Electric dipole moments (EDMs) of nucleons and nuclei are actively considered as direct evidence of the CP violation. Calculations of nucleon EDMs are required to connect the quark- and hadron- level effective CP violating interactions within QCD or other CP violating sources in new physics beyond the standard model. Precise and model-independent relations between nucleon EDM and various sources of CP violation are expected from QCD calculations on a lattice. I will review recent progress on lattice calculations of nucleon EDM induced by lowest-order quark-gluon operators and their implications for EDM experiments as well as show some recent preliminary results.
