Quark/gluon content of eta(1295) and eta(1440) | | A. V. Anisovich
; | | Date: |
1 Apr 2001 | | Subject: | hep-ph | | Abstract: | 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)%. | | Source: | arXiv, hep-ph/0104005 | | Services: | Forum | Review | PDF | Favorites | |
