Transverse parton distribution functions at next-to-next-to-leading order: the quark-to-quark case.
We present a calculation of the perturbative quark-to-quark transverse parton distribution function at next-to-next-to-leading order based on a gauge invariant operator definition. We demonstrate for the first time that such a definition works beyond the first nontrivial order. We extract from our calculation the coefficient functions relevant for a next-to-next-to-next-to-leading logarithmic Q...
متن کاملCharm Quark Contribution to K → πνν̄ at Next-to-Next-to-Leading Order
We calculate the complete next-to-next-to-leading order QCD corrections to the charm contribution of the rare decay K → πνν̄. We encounter several new features, which were absent in lower orders. We discuss them in detail and present the results for the twoloop matching conditions of the Wilson coefficients, the three-loop anomalous dimensions, and the two-loop matrix elements of the relevant op...
متن کاملCharm Quark Contribution to K L → μ + μ − at Next - to - Next - to - Leading Order
We calculate the charm quark contribution to the decay KL → μ μ in next-to-next-to-leading order of QCD. This new contribution reduces the theoretical uncertainty in the relevant parameter Pc from ±22% down to±7%, corresponding to scale uncertainties of±3% and ±6% in the short-distance part of the branching ratio and the determination of the Wolfenstein parameter ρ̄ from KL → μ μ. The error in P...
متن کاملEnergy dependence of mean multiplicities in gluon and quark jets at the next-to-next-to-next-to-leading order
Analytic predictions for the energy dependence of the mean multiplicities in gluon and quark jets are presented at the next-to-next-tonext-to-leading order (3NLO) of perturbative QCD and are compared to experiment. The 3NLO correction to the gluon jet multiplicity is found to be small. The corresponding theoretical expression provides a good description of available gluon jet measurements. In c...
متن کاملNext-to-next-to-leading-order logarithmic corrections at small transverse momentum in hadronic collisions
We study the region of small transverse momenta in q&qmacr;- and gg-initiated processes with no colored particle detected in the final state. We present the universal expression of the O(alpha(2)(s)) logarithmically enhanced contributions up to next-to-next-to-leading-order logarithmic accuracy. From there we extract the coefficients that allow the resummation of the large logarithmic contribut...
