Description
Among the parameters of QCD is one that results in CP violation when
non-vanishing. This is closely related to possible quark mass terms.
It is conventionally interpreted in terms of gauge field topology or
alternatively in terms of real chiral eigenvalues of the Dirac
operator. There is no experimental evidence for this parameter having
a non-zero value, a puzzle for theories involving unification.
