The gluon contents of the eta and eta' mesons
arXiv:hep-ph/0310311 · doi:10.1063/1.1799748
Abstract
It is reported on a leading-twist analysis of the eta - photon and eta' - photon transition form factors. The analysis allows for an estimate of the lowest Gegenbauer coefficients of the quark and gluon distribution amplitudes.
