Figures and Data Archive
For each figure we provide an encapsulated Postscript and gif version. The data is presented in
ASCII files with small headers lines starting with the # character,
followed by single tab separated columns.
WORD OF CAUTION: These invariant yields were extracted to calculate the RdAu ratios, we did not unfold the
momentum resolution, all data points are located at the pt where the function describing the distribution is equal to the
number of counts in the bin. We follow the recomendation of NIM A355 (1995) 541-547, a single mean value
of pseudo-rapidity was allocated to each distribution.

This figure shows the spectra for charged particles produced in p+p and d+Au collisions.
At eta=0, we show the distribution of average charge (h^+ + h^-)/2 measured in
p+p collisions, and d+Au collisions. All data points are placed
at the center of the bin.
At eta=1, we show the distribution of average charge (h^+ + h^-)/2 measured in
p+p collisions, and d+Au collisions. All data points are placed
at the center of the bin.
At eta=2.2, we show the distribution of negative charge hadrons h^- measured in
p+p collisions, and d+Au collisions. All data
points are placed at the center of the bins.
At eta=3.2, we show the distribution of h^- measured in
p+p collisions, and d+Au collisions. All data
points are placed at the center of the bins.

At eta=0 we show the nuclear modification factor RdAu eta=0 .
this ratio was calculated with the data of the d+Au distribution and a fit to the p+p distribution.
The functional form of that fit is the power law:
(1/2pi)dn/deta (n-1)(n-2)/p0^2 (1 + pt/p0)^-n
where dn/deta = 1.06, p0 = 1.9, n=11.67
At eta=1 we show the nuclear modification factor RdAu eta=1 .
this ratio was calculated with the data of the d+Au distribution and a fit to the p+p distribution
with the same power law shape as the fit done at eta=0:
the parameters for that fit where: dn/deta = 1.41, p0 = 1.58, n=10.9
At eta=2.2 we show the nuclear modification factor RdAu eta=2.2 .
At eta=3.2 we show the nuclear modification factor RdAu eta=3.2 .

The "central" events at eta=0 are presented in Rcp central eta=0
and the "semi central" events are shown in Rcp semi-central
eta=0.
The "central" events at eta=1 are presented in Rcp central eta=1
and the "semi central" events are shown in Rcp semi-central
eta=1.
The "central" events at eta=2.2 are presented in Rcp central eta=2.2
and the "semi central" events are shown in Rcp semi-central
eta=2.2.
The "central" events at eta=3.2 are presented in Rcp central eta=3.2
and the "semi central" events are shown in Rcp semi-central
eta=3.2.
