نویسنده
چکیده
A consistent phenomenological approach to the computation of transverse single spin asymmetries in inclusive hadron production is presented, based on the assumed generalization of the QCD factorization theorem to the case in which quark intrinsic motion is taken into account. New k⊥ and spin dependent quark distribution and fragmentation functions are considered: some of them are fixed by fitting data on pp → πX and predictions are given for single spin asymmetries in lp → πX and γp → πX processes.

Exciting and even unexpected results have been presented in the sessions about “polarized lepton nucleon scattering”, at the DIS 99 workshop. Most striking are the presentations of the flavor decomposition of the quark polarization, the first direct observation of a positive gluon polarization in the nucleon and the observation of a double-spin asymmetry in diffractive ρ production. First resul...
