Charged particle distributions and nuclear modification at high rapidities in d + Au collisions at s(NN)**(1/2) = 200-GeV

200 GeV are reported. They provide a sensitive tool for understanding the dynamics of multi-particle production in the high parton-density regime. In particular, we observe strong suppression of the nuclear modification factor

R_{CP}

at forward rapidities (d-side,

\eta

= 3.1) and enhancement at backward rapidity (

\eta

=

-

3.1). An empirical scaling is obtained for multiplicity and

R_{CP}

when a shift of the center-of-mass in the asymmetric d+Au collisions with respect to the nucleon-nucleon system is applied.
