- W1999339733 abstract "One- and two-photon decays of meson resonances are calculated in a quark-oscillator model using a nonrelativistic interaction Hamiltonian and vector dominance. Harmonic-oscillator wave functions are assumed for $l=0$ and $l=1$ resonances (e.g., $ensuremath{pi}$, $ensuremath{rho}$ and ${A}_{2}$, $f$, respectively). The calculations in general are sensitive to the value of the well-width parameter ${ensuremath{alpha}}^{2}$. Good agreement with experiment is obtained for decays of low-lying states (such as ${ensuremath{pi}}^{0}$ and $ensuremath{eta}$) and for the decay ${A}_{2}^{ifmmodepmelsetextpmfi{}}ensuremath{rightarrow}{ensuremath{pi}}^{ifmmodepmelsetextpmfi{}}+ensuremath{gamma}[ensuremath{Gamma} (mathrm{predicted})=0.4ensuremath{-}0.6 mathrm{MeV}]$. The calculated width for the decay $f(1260)ensuremath{rightarrow}ensuremath{gamma}ensuremath{gamma}$ is less than that predicted by Kunzst et al., on the basis of a phenomenological Lagrangian by a factor of 3 or more." @default.
