Azimuthal and spin asymmetries in DIS
In these lectures I want to discuss how the structure functions in deep inelastic scattering relate to quark and gluon correlation functions. In particular we will consider the issue of intrinsic transverse momenta of quarks, which becomes important in processes like 1-particle inclusive leptoproduction. Some examples of cross sections and asymmetries, in particular in polarized scattering proc...
متن کاملSingle Spin Asymmetries in Dis
We consider possible mechanisms for single spin asymmetries in inclusive Deep Inelastic Scattering (DIS) processes with unpolarized leptons and transversely polarized nucleons. Tests for the effects of non-zero intrinsic k⊥, for the properties of spin dependent quark fragmentations and for quark helicity conservation are suggested. Single spin asymmetries in large pT inclusive hadronic reaction...
متن کاملSingle Spin Asymmetries and Vector Meson Production in Dis * Single Spin Asymmetries in Dis
We discuss possible measurements and origins of single spin asymmetries in DIS and of some unusual spin properties of vector mesons produced in lN , γN and γγ interactions. Such effects have already been observed in other processes. Single spin asymmetries in DIS Single spin asymmetries in large p T inclusive hadronic reactions are forbidden in leading-twist perturbative QCD, reflecting the fac...

متن کاملSingle - spin Azimuthal Asymmetries in the “ Reduced Twist - 3 Approximation ”
We consider the single-spin azimuthal asymmetries recently measured at the HERMES experiment for charged pions produced in semi-inclusive deep inelas-tic scattering of leptons off longitudinally polarized protons. Guided by the experimental results and assuming a vanishing twist-2 transverse quark spin distribution in the longitudinally polarized nucleon, denoted as " reduced twist-3 approximat...
