- W2005200475 abstract "For a class of hindered magnetic-dipole ($M1$) transition processes, such as $ensuremath{Upsilon}(3S)ensuremath{rightarrow}{ensuremath{eta}}_{b}+ensuremath{gamma}$ (the discovery channel of the ${ensuremath{eta}}_{b}$ meson), the emitted photon is rather energetic so that the traditional approaches based on multipole expansion may be invalidated. We propose that a ``hard-scattering'' picture, somewhat analogous to the pion electromagnetic form factor at large momentum transfer, may be more plausible to describe such types of transition processes. We work out a simple factorization formula at lowest order in the strong coupling constant, which involves convolution of the Schrodinger wave functions of quarkonia with a perturbatively calculable part induced by exchange of one semihard gluon between quark and antiquark. This formula, without any freely adjustable parameters, is found to agree with the measured rate of $ensuremath{Upsilon}(3S)ensuremath{rightarrow}{ensuremath{eta}}_{b}+ensuremath{gamma}$ rather well, and can also reasonably account for other recently measured hindered $M1$ transition rates. The branching fractions of $ensuremath{Upsilon}(4S)ensuremath{rightarrow}{ensuremath{eta}}_{b}^{(ensuremath{'})}+ensuremath{gamma}$ are also predicted." @default.
