Inclusive Prompt Photon Production in Polarized pp Collisions at HERA-N
L. E. Gordon, W. Vogelsang
Abstract
We present a NLO study of inclusive polarized prompt photon production in a conceivable fixed target pp mode of HERA with longitudinally polarized protons at s=39 GeV. We analyze the sensitivity of the corresponding double spin asymmetry to the proton's polarized gluon distribution Δg and estimate the expected statistical precision in its determination. The main theoretical uncertainties in the predictions are examined.
