Pseudoscalar Meson Decay Constants and Couplings, the Witten-Veneziano Formula beyond large N_c, and the Topological Susceptibility
G. M. Shore
The QCD formulae for the radiative decays $η,η'\to\c\c$, and the corresponding Dashen--Gell-Mann--Oakes--Renner relations, differ from conventional PCAC results due to the gluonic…

Target Fragmentation at Polarized HERA: A Test of Universal Topological Charge Screening in QCD
D. de Florian, G. M. Shore, G. Veneziano
Topological charge screening has been proposed as the mechanism responsible for the anomalous suppression in the first moment of the polarized proton structure function -- the `pro…
