An exact sum rule for transversely polarized DIS
The Operator Product Expansion provides expressions for the nth moments of g1(x) and g2(x) in terms of hadronic matrix elements of local operators for n = odd integer. In some cases these matrix elements are expected to be small leading to approximate sum rules for the odd moments of g1,2(x). We have shown how, working in a field-theoretic framework, one can derive expressions for the even mome...
متن کاملSeaQuest with a Transversely Polarized Target (E1039)
We have constructed a state-of-the-art, high luminosity polarized proton and deuteron target and propose to measure the Sivers asymmetry for the ū and d̄ sea quarks in the nucleon for four different Bjorken xB bins in the range 0.1 < xB < 0.5, using the Drell-Yan process at SeaQuest. We will: i) perform the first measurement of the Sivers asymmetry in Drell-Yan scattering for sea quarks; ii) det...
متن کاملLongitudinal 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 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 کامل0 Transversely polarized Λ production 1
Transversely polarized Λ production in hard scattering processes is discussed in terms of a leading twist T-odd fragmentation function which describes the fragmentation of an unpolarized quark into a transversely polarized Λ. We focus on the properties of this function and its relevance for the RHIC and HERMES experiments.
