Heavy-quarkonium creation and annihilation with O(alphas3 ln(alphas)) accuracy
Abstract
We calculate the O(alphas3 ln(alphas)) contributions to the heavy-quarkonium production and annihilation rates. Our result sheds new light on the structure of the high-order perturbative corrections and opens a new perspective for a high-precision theoretical analysis. We also determine the three-loop anomalous dimensions of the nonrelativistic vector and pseudoscalar currents.
