  First, we show how to reduce the sensitivity of the NLO predictions of the
Drell-Yan production of low-mass, lepton-pairs, at high rapidity, to the choice
of factorization scale. In this way, observations of this process at the LHC
can make direct measurements of parton distribution functions in the low x
domain; x < 10^{-4}. Second, we find an inconsistency in the conventional NLO
treatment of the infrared region. We illustrate the problem using the NLO
coefficient function of Drell-Yan production.
