摘要: Abstract The conventional theory for the lack of U(1) chirality invariance in presence topological charge v fails to resolve problem: it involves selection rules which forbid changes ± 2 needed generate charged-pion decay constant F π . Possible remedies are considered; if they work. is proportional average value per unit Euclidean volume.
