A Phenomenological Analysis of Gluon Mass Effects in Inclusive Radiative Decays of the $\rm{J/\psi}$ and $\Upsilon$
The shapes of the inclusive photon spectra in the processes $\Jp \to \gamma X$ and $\Up \to \gamma X$ have been analysed using all available experimental data. Relativistic, higher order QCD and gluon mass corrections were taken into account in the fitted functions. Only on including the gluon mass...
