Extraction of alpha_s from radiative Upsilon(1S) decays
Nora Brambilla, Xavier Garcia i Tormo, Joan Soto +1
We improve on a recent determination of alpha_s from Gamma(Upsilon(1S)-->X gamma)/Gamma(Upsilon(1S)-->X) with CLEO data by taking into account color octet contributions and avoidin…

Inclusive radiative decays of charmonium
Xavier Garcia i Tormo, Joan Soto
We discuss the theoretical status of inclusive radiative decays of charmonium, with a particular emphasis on the QCD description of the photon spectrum, where progress has occurred…

Octet contributions in radiative upsilon decays
Xavier Garcia i Tormo
We analyze the end-point region of the photon spectrum in semi-inclusive radiative decays of very heavy quarkonium (m alpha_s^2 >> Lambda_QCD). The S- and P-wave octet shape functi…
