Description:
Author(s): N. F. Nasrallah The couplings of the isosinglet axial-vector currents to the η and η ′ mesons are evaluated in a stable, model-independent way by use of polynomial kernels in dispersion integrals. The corrections to the Gell-Mann–Oakes–Renner relation in the isoscalar channel are deduced. The derivative of the topol… [Phys. Rev. D 95, 033001] Published Mon Feb 13, 2017
