AbstractWe re-investigate the vector and axial-vector vacuum susceptibilities by, taking advantage of the vector and axial-vector Ward-Takahashi identities. We show analytically that, in the chiral limit, the vector vacuum susceptibility is zero and the axial-vector vacuum susceptibility equals three fourths of the Square of the pion decay constant. Besides, our analysis reproduces the Weinberg sum rule. (C) 2008 Elsevier B.V. All rights reserved.
