{QCD} Sum Rules and Hybrid Mesons
TL;DR: In this paper, a general background field method is presented to compute operator product expansions in the framework of QCD sum rules for operators coupling to hybrid mesons, and the masses and couplings of quark-antiquark-gluon states with JPC = 1−+, 1+−, 0++, 0−− and I = 0, 1.
Journal ArticleDOI
Exotic mesons from qcd sum rules
TL;DR: In this paper, a simple method was presented to compute the Wilson expansion coefficients for T-products in QCD with light quarks, using this method in the framework of QCD sum rules they predicted the masses of quark-antiquark-gluon states with JPC = 1−+, 0++, 1+− and 0−−.

Anomalous Ward identities and psi rarr gamma eta ( eta '), psi ' rarr psi pi /sup 0/( eta ) decay rates
D. Gusbin,D. Verstegen +1 more
TL;DR: Anomalous Ward identities saturated with one-particle pseudoscalar states, together with pi /sup 0/, eta and eta'rarr 2 gamma decay amplitudes, provide a set of equations which can be solved for the axial-vector couplings and the topological charge components as discussed by the authors.
