Longitudinal quark polarization in transversely polarized nucleons.
Intrinsic transverse momentum (kT) plays an important role in the quark distribution functions ~DF’s! used to describe a polarized nucleon @1,2#. For the leading ~twist-two! part of the deep inelastic scattering cross section one already needs six DF’s to describe the quark state in a polarized nucleon. They depend on x and kT 2 , which parametrize the quark momentum in a nucleon with momentum ...
متن کاملNIKHEF 95-059 YERPHI-1455(25)-95 Longitudinal quark polarization in transversely polarized nucleons
Accounting for transverse momenta of the quarks, a longitudinal quark spin asymmetry exists in a transversely polarized nucleon target. The relevant leading quark distribution g1T (x; k 2 T) can be measured in the semi-inclusive deep-inelastic scattering. The average k T weighted distribution function g (1) 1T can be obtained directly from the inclusive measurement of g2. Intrinsic transverse m...
متن کاملGluon polarization in transversely polarized nucleons and jet spin asymmetries at RHIC
We derive the analog of the Wandzura-Wilczek relation for the light-cone distributions of polarized gluons in a transversely polarized nucleon. The short distance cross-section is entirely due to the intrinsic transverse momenta of gluon in the nucleon, in complete analogy to the quark case. Numerical estimate for the double spin transverse asymmetries at RHIC are presented. PACS. 12.38.Bx, 13....
متن کاملSpin effects in the fragmentation of a transversely polarized quark
An azimuthal dependence of pions produced in polarized Deep Inelastic Scattering, γp → πX, has been recently observed and might be related to the so-called Collins effect. We discuss in details, for a general spin configuration of the nucleon, the kinematics of the process and methods of extracting information on the fragmentation properties of a polarized quark. Assuming that the observed azim...
متن کاملTHE ROLE OF QUARK POLARIZATION IN HEAVY QUARK FRAGMENTATION
We calculate the exact fragmentation functions for c and b quark fragmentation taking into account the spin orientation of the initial heavy quark in the form of analytical and rather simple expressions. Our calculations show that spin orientation may have an important effect on the fragmentation spectrum. This effect is more striking in the cases of c ?D, D*; c? ? , ? , and ?B , B *.
