  • Following an earlier derivation by Catani-de Florian-Grazzini (2000) on the scheme dependence in the Collins-Soper- Sterman (CSS) resummation formalism in hard scattering processes, we investigate the scheme dependence of the Transverse Momentum Distributions (TMDs) and their applications. By adopting a universal C-coefficient function associated with the integrated parton distributions, the difference between various TMD schemes can be attributed to a perturbative calculable function depending on the hard momentum scale. Thus, we further apply several TMD schemes to the Drell-Yan process of lepton pair production in hadronic collisions, and find that the constrained non-perturbative form factors in different schemes are remarkablymore » consistent with each other and with that of the standard CSS formalism.« less

  • We study the nonperturbative functions in the Collins-Soper-Sterman resummation formalism by examining Drell-Yan data in both fixed target and collider experiments and then predict the transverse momentum distributions of the [ital W][sup [plus minus]] and [ital Z][sup 0] bosons at the Fermilab Tevatron. Our results differ from those in the literature and agree better with published CDF data. Using statistical arguments, we find a 1 fb[sup [minus]1] luminosity at the Tevatron should be able to provide useful constraints on the nonperturbative functions.
  • The hadron-energy evolution (Collins and Soper) equation for all the leading-twist transverse-momentum and spin dependent parton distributions is derived in the impact parameter space. Based on this equation, we present a resummation formulas for the spin dependent structure functions of the semi-inclusive deep-inelastic scattering.
