> Dear Tom, Wit, Tim and Flemming:
>
> I am pleased to announce that the PHENIX collaboration intends to submit
to Physical Review Letters in one week's time a manuscript on hadron
production in the 'forward' and 'backward' regions in d+Au collisions. The
title and abstract are included below.

Rapidities in
> Deuteron-Gold Collisions at √sNN = 200 GeV
>
> Abstract: We report on charged hadron production in deuteron-gold
reactions at √sNN = 200 GeV. Our
> measurements in the deuteron-direction cover 1.4 < eta < 2.2, referred to
as forward rapidity, and in
> the gold-direction −2.0 < eta < −1.4, referred to as backward rapidity,
and a transverse momentum
> range pT = 0.5 − 4.0 GeV/c. We compare the relative yields for different
deuteron-gold collision
> centrality classes. We observe a suppression relative to binary collision
scaling at forward rapidity,
> sensitive to low momentum fraction (x) partons in the gold nucleus, and an
enhancement at backward
> rapidity, sensitive to high momentum fraction partons in the gold nucleus.
