Hybrid Quarkonium Masses up to the order of O(1/mQ)

We have calculated the binding energy of the hybrid quarkonium up to the order of O(1/mQ) and found their decay constants scale like m 5 4 Q as mQ → ∞. The 0 and 0++ hybrid quarkonium is exactly degenerate in the limit mQ → ∞ while the O(1/mQ) correction renders the 0 mass lower than that for 0++. The 1−+ and 1+− hybrid is nearly degenerate and lies 0.7 GeV lower than the 0. With mb = 4.8GeV th...

Light Quark Masses and Quarkonium Decays

After discussing the intrinsic ambiguity in determining the light quark mass ratio mu/md, we reexamine the recent proposal that this ambiguity can be resolved by applying the QCD multipole expansion for the heavy quarkonium decays. It is observed that, due to instanton effects, some matrix elements which have been ignored in previous works can give a significant contribution to the decay amplit...

Quarkonium Decays and Light Quark Masses

The SU(3)-violating decays Φ →ΦX , where X = π or η and Φ = J/ψ or Υ have been recently proposed as a means of probing the light quark masses beyond leading order in chiral perturbation theory. We argue that this analysis is incorrect, even in the heavy quark limit. We show that these decays are governed by an infinite number of matrix elements which are not suppressed by any small parameter, a...

Heavy-quarkonium Production at Next-to-leading Order

The factorization formalism of nonrelativistic quantum chromodynamics (NRQCD) provides a rigorous theoretical framework for the description of heavy-quarkonium production and decay that is renormalizable and predictive.1 Theoretical predictions are decomposed into sums over products of short-distance coefficients, which can be calculated perturbatively as expansions in the strong-coupling const...

Electromagnetic quarkonium decays at order v

We compute S-wave and P-wave electromagnetic quarkonium decays at order v7 in the heavy-quark velocity expansion. In the S-wave case, our calculation confirms and completes previous findings. In the P-wave case, our results are in disagreement with previous ones; in particular, we find that two matrix elements less are needed. The cancellation of infrared singularities in the matching procedure...
