The First Moment of δg(x) - a Comparative Study

Authors: Bodo Lampe, Andreas Ruffing

The sensititivity of various future polarization experiments to the first moment Δg of the polarized gluon density is elucidated in detail. It is shown to what extent the first moment can be extracted from the future data as compared to the higher moments. We concentrate on two processes which in the near future will become an important source of information on the polarized gluon density, namely the photoproduction of open charm to be studied at CERN (COMPASS) and SLAC and the production of direct photons at RHIC.
