Fragmentation of Transversely Polarized Quarks Probed in Transverse Momentum Distributions
It is shown that the azimuthal dependence of the distribution of hadrons in a quark jet is a probe of the transverse spin of the quark initiating the jet. This results in a new spin-dependent fragmentation function that acts at the twist-2 level. One example of a process where it contributes is semi-inclusive deeply inelastic scattering with a transversely polarized nucleon target but with an u...
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 کاملLongitudinally Polarized Colliding Beams
The feasibility of experiments with the polarized colliding beams expands significantly possibilities of getting information on fundamental interactions. Even the use of the transversely polarized beams enables getting the more reliable and clear definition of spins for the intermediate states and final particles,1p2 as well as to introduce the precise absolute energy scale.3-s But only the use...
متن کاملLow-Energy Compton Scattering of Polarized Photons on Polarized Nucleons
The general structure of the cross section of γN scattering with polarized photon and/or nucleon in initial and/or final state is systematically described and exposed through invariant amplitudes. A low-energy expansion of the cross section up to and including the order O(ω4) is given which involves ten structure parameters of the nucleon (dipole, quadrupole, dispersion, and spin polarizabiliti...
متن کاملTransverse Force on Quarks in DIS
Generalized Parton Distributions (GPDs) provide information on the distribution of quarks in impact paarmeter space. For transversely polarized nucleons, these impact parameter distributions are transversely distorted and this deviation from axial symmetry leads on average to a net transverse force from the spectators on the active quark in a DIS experiment. This force when acting along the who...
