Physics at the B Factories
T. E. Browder
We review recent progress at the two B factories. The first measurement of CP violation and the prospects for measuring all the angles of the unitarity triangle are discu…
New predictions for inclusive heavy-quarkonium P-wave decays
N. Brambilla, D. Eiras, A. Pineda +2
We show that some NRQCD colour-octet matrix elements can be written in terms of (derivatives of) wave functions at the origin and non-perturbative universal constants once the fact…
Poincare' invariance and the heavy-quark potential
Nora Brambilla, Dieter Gromes, Antonio Vairo
We derive and discuss the constraints induced by Poincare' invariance on the form of the heavy-quark potential up to order 1/m^2. We present two derivations: one uses general argum…
Quarkonium Spectroscopy and Perturbative QCD: A New Perspective
N. Brambilla, Y. Sumino, A. Vairo
We study the energy spectrum of bottomonium in perturbative QCD, taking alpha_s(Mz)=0.1181 +/- 0.0020 as input and fixing m_b^{MSbar}(m_b^{MSbar}) on the Upsilon(1S) mass. Contrary…
