Probing the QCD θ ¯ $$ \overline{\theta} $$ term with paramagnetic molecules
Abstract The experimental search for CP violation in paramagnetic atomic and molecular systems has made impressive progress in recent years. This has led to strong upper limits on the electron electric dipole moment. The same measurements can also be used to constrain hadronic sources of CP violatio...
