Azimuthal Spin Asymmetries in Semi-Inclusive Production from Positron-Proton Scattering
arXiv:hep-ph/0001196 · doi:10.1016/S0370-2693(00)00285-9
Abstract
The recent measurements of azimuthal single spin asymmetries by the HERMES collaboration at DESY may shed some light on presently unknown fragmentation and distribution functions. We present a study of such functions and give some estimates of weighted integrals directly related to those measurements.
