Revisiting the Vector and Axial-vector Vacuum Susceptibilities
Lei Chang, Yu-xin Liu, Wei-min Sun +1
We 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 th…

Flavour symmetry breaking and meson masses
Mandar S. Bhagwat, Lei Chang, Yu-Xin Liu +2
The axial-vector Ward-Takahashi identity is used to derive mass formulae for neutral pseudoscalar mesons. Flavour symmetry breaking entails non-ideal flavour content for these stat…
