Determination of the QCD coupling from the static energy and the free energy
Alexei Bazavov, Nora Brambilla, Xavier Garcia i Tormo +4
We present two determinations of the strong coupling \(α_s\). The first one is from the static energy at three-loop accuracy, and may be considered an update of earlier determinati…
Factorization theorems for exclusive heavy-quarkonium production
Geoffrey T. Bodwin, Xavier Garcia i Tormo, Jungil Lee
We outline the proofs of the factorization theorems for exclusive two-body charmonium production in B-meson decay and e^+e^- annihilation to all orders in perturbation theory in qu…
Radiative decays and the nature of heavy quarkonia
Xavier Garcia i Tormo, Joan Soto
We argue that the photon spectra in radiative decays of various heavy quarkonium states provide important information on their nature. If two of these states are in the strong coup…
