| dc.description | The quark/gluon content of eta(1295) and eta(1440) mesons is discussed, mesons being considered as members of the first radial excitation 2^1S_0 qqbar nonet. Recent results on eta(1295) and eta(1440) two-photon widths from L3 together with the information on radiative J/Psi decay allow one to evaluate the eta(1295)/eta(1440) mixing angle and the admixture of the glueball component. We found that eta(1440) is dominantly non-strange qqbar state, with a possible admixture of the glueball component (20 pm 20)%. | |
