Eta' meson as a pseudoscalar gluonium
- 1. Institute of Theoretical and Experimental Physics, Moscow, USSR
Description
QCD sum sules induced by the current Gsub(μγ)sup(a) Gsub(μγ)sup(a) tilde constructed from gluon field operators are derived. Saturating the sum rules of eta' rough estimates for the eta' mass and its residue are found. The difference between the eta' and typical quark states such as rho is noted. Breaking of the operator expansion by the instanton effects is discussed. (Auth.)
