چکیده
The twist-four quark and gluon distributions in a transversely polarized nucleon are identified and relations among them are discussed by using QCD equations of motion. Their contribution, at the order of O ( 1/Q ) , to the Drell-Yan cross section in transversely polarized nucleon-nucleon collisions is calculated. Submitted to: Phys. Rev.

متن کاملResummation in Transversely Polarized Drell - Yan Process
Hard processes with polarized nucleon beams enable us to study spin-dependent dynamics of QCD and the spin structure of nucleon. The helicity distribution ∆q(x) of quarks within nucleon has been measured in polarized DIS experiments, and ∆G(x) of gluons has also been estimated from the scaling violations of them. On the other hand, the transversity distribution δq(x), i.e. the distribution of t...
متن کاملALT in the polarized Drell-Yan process at RHIC and HERA energies
We present a leading order (LO) estimate for the longitidinal-transverse spin asymmetry (ALT ) in the nucleon-nucleon polarized Drell-Yan process at RHIC and HERA~ N energies in comparison with ALL and ATT . ALT receives contribution from g1, the transversity distribution h1, and the twist-3 distributions gT and hL. For the twist-3 contribution we use the bag model prediction evolved to a high ...

متن کاملDouble-Spin Asymmetry ALT for Polarized Drell-Yan Process in pp̄ Collisions: Wandzura-Wilczek Contribution
The longitudinal-transverse spin asymmetry ALT in the polarized Drell-Yan process depends on twist-3 quark distributions of nucleon. In addition to the contributions associated with the twist-3 operators, these distributions contain the “Wandzura-Wilczek (WW)” part, which is determined by a certain integral of twist-2 distributions. The recently obtained empirical information on the transversit...
