Vacuum orientations in strong CP violation

PDF Version Also Available for Download.

Description

We study the QCD vacuum orientation angles in correlation with the strong CP phases. A vacuum alignment equation of the dynamical chiral symmetry breaking is derived based on the anomalous Ward identity. It is emphasized that a chiral rotation of the quark field causes a change of the vacuum orientation and a change in the definition of the light pseudoscalar generators. As an illustration of the idea, {eta} {yields} 2{pi} decays are carefully studied in different chiral frames and shown to be independent of. chiral rotations.
