Radiative decays of heavy mesons into paraquarkonia
Description
The width for decays of the type 1- → γ + 0- is evaluated using the two gluon mechanism of QCD. In particular we compute GAMMA(psi → γ + eta'), GAMMA(psi → γ + eta) and GAMMA(UPSILON → γ + etasub(c)). The first two are found to be in reasonable agreement with the experimental results, while the latter leads to a branching ratio of 2 x 10-5. (orig.)
