The endpoint region in radiative quarkonia decays
F. Hautmann
We consider the inclusive radiative decays quarkonium -> gamma + hadrons and examine the effects of soft QCD radiation on the photon energy spectrum near the endpoint.

A gauge-invariant subtraction technique for non-inclusive observables in QCD
F. Hautmann
Using the electromagnetic form factor of a quark as a working example, we describe a subtraction technique to treat infrared sensitive regions in non-inclusive processes.

Cancellation of Sudakov Logarithms in Radiative Decays of Quarkonia
F. Hautmann
We study infrared QCD effects in radiative quarkonia decays. We examine the endpoint region z -> 1 of the photon spectrum. We point out a cancellation mechanism for the corrections…
