Polarized quarks and quantum chromodynamics
Dremin I.M., Nazirov M.T.
We calculate the cross section for the scattering of ultrarelativistic polarized quarks in quantum chromodynamics in the Born approximation, which is valid at large momentum transfer because of asymptotic freedom. We discuss possible applications to elastic large-angle scattering of polarized protons, to production of particles with large transverse momenta, and to lepton-pair production processes in interaction of polarized hadrons.
