Abstract:

We discuss γγ partial widths of pseudoscalar/isoscalar mesons η:(M) in the mass region M∼ 1000–1500 MeV. The transition amplitudes η:(1295) →γγ and η:(1440) →γγ are studied within an assumption that the decaying mesons are the members of the first radial excitation nonet 21 S 0q¯q. The calculations show that partial widths being of the order of 0.1 keV are dominantly due to the n¯n meson component while the contribution of the s¯s component is small.
