Can Polarised Drell-Yan Shed More Light On The Proton Spin?
arXiv:hep-ph/9208208 · doi:10.1142/S0217732392002159
Abstract
We analyse polarised Drell-Yan process using the factorisation method and derive operator definitions for polarised parton distribution functions. We demonstrate that a factorisation analogous to that in the unpolarised Drell-Yan case holds in this process. We study the leading order gluonic contribution to the first moment of polarised Drell-Yan function and show that it is consistent with results obtained from polarised deep inelastic scattering.
