Measuring the Gluon Helicity Difference Distribution Function of the Proton using Photoproduction Processes

Abstract

Little information is known about the polarization of gluons inside a longitudinally polarized proton. I report on the sensitivity of photoproduction experiments to it. Both jet and heavy quark production are considered.
