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… (More)
