Aspects of and Production in Polarized Proton-Proton Collisions
Several topics of relevance to low transverse momentum and
production in polarized proton-proton collisions
are discussed. The leading contributions to the low
production cross-sections via , , and
initial states are calculated as well as the corresponding spin-spin
asymmetries. We find that production increases relative to direct
and production, providing up to of the observable
pairs arising from decays in collisions at . The spin-dependence of production, however, is much smaller
than for either direct or production and so will likely be far
less useful than either process in probing the polarized gluon structure
function of the proton. A subset of the radiative
corrections to production involving initial state quarks are also
performed and compared to leading order predictions.Comment: 21 pages + 5 postscript figures (included), OCIP/C-94-
