TL;DR: Weinberg's spectral function sum rules were examined to study the axial vector mass spectrum at the level of SU(4) in this paper, where new mass relations and general mass constraints were derived to predict the masses of the charmed axial vectors and the I = 0 pseudoscalar decay constants.

Spectral-Function Sum Rules with Symmetry Breaking
Tomoya Akiba,Kyungsik Kang +1 more
TL;DR: In this paper, the symmetry breaking based on Okubo's ansatz is considered to modify Weinberg's spectral function sum rules (particularly the second), and the modified sum rules are applied to the chiral $U(3)$ and obtain physically interesting results for the mass relation and mixing angles of the vector mesons, a nonet assignment of the axialvector mesons and the decay constants of the pseudoscalar mesons.
