We report the first observation of Upsilon(2S)-->etaUpsilon(1S), with a branching fraction B=(2.1(-0.6)+0.7(stat)+/-0.3(syst)) x 10(-4) and a statistical significance 5.3sigma. Data were acquired with the CLEO III detector at the CESR e+e(-) symmetric collider. This is the firs...

The decays of $\Upsilon(1s)\to\gamma(\eta',\eta)$ are studied by an approach which has successfully predicted the ratio $\frac{\Gamma(J/\psi\to\gamma\eta')}{\Gamma(J/\psi\to\gamma\eta)}$. Strong dependence on quark mass has been found in the decays $(J/\ps ...
In this work, we investigate the re-scattering effects in the radiative decay $\\Upsilon(5S)o\\eta_b+\\gamma$, which were suggested to be crucially important for understanding the anomalous largeness of the branching ratios $B(\\Upsilon(5S)o \\Upsilon(1S)+\\pi\\pi)$ and $B(\\Upsil...
We calculate the decay constant ratios $f_{\eta_c}/f_{J/\psi}$ and$f_{\eta_b}/f_\Upsilon$. In the calculation we take into account the mock mesonstructures of the mesons, as well as the difference of the wave functions atorigin of the vector and pseudoscalar mesons studied ...
