Welcome to RHIC News
We hope that this web publication will in some small measure reflect the excitement of the RHIC and AGS program at Brookhaven, as explained by some of the people who are doing the experiments, analyzing the data, and writing the papers.
RHIC
Funding, Operating Schedule Update
By Steven Vigdor
I have now secured enough funds to run RHIC for a total of 19
cryoweeks, i.e., until mid-March, allowing essentially 6 weeks
beyond the end of the d+Au portion of the run. Everyone agreed
that this was insufficient time to permit a meaningful addition
to precision of constraints on gluon polarization from
incremental longitudinal spin asymmetries in 200 GeV pp. More...
Evidence
for Color Transparency and Direct Hadron Production at RHIC
By Stanley J. Brodsky
The QCD color transparency of higher-twist contributions to the
inclusive hadroproduction cross section where the trigger proton
is produced directly in a short-distance subprocess can explain
several remarkable features of high-pT proton production in
heavy ion collisions which have recently been observed at RHIC More...
Granular
Jets as a Classical Analog of RHIC Collisions
By Xiang Cheng, Heinrich Jaeger and Sidney Nagel
After a cylindrical stream of non-cohesive granular particles
hits a target, a thin sheet of particles emerges in the plane
normal to the initial direction of the jet. Although particulate
in nature, the granular jet behaves like a liquid with zero
surface tension if the density of collisions is high enough [1].
For jets with an elongated cross-section, the resulting spray is
collimated and emerges from the long side of the collision
region. This appears to be a classical analog of the elliptic
anisotropic flow observed at RHIC for the quark-gluon plasma..

QuarkNet
in BNL
By Helio Takai
I am sure that many of you have heard about QuarkNet, or at
least I hope you did. QuarkNet [1] is a particle physics
education and outreach program that started in 1999 and it has
been growing in size ever since. Its main goal (as stated in the
web site) is to bring together high school students, teachers
and physicists to explore the hidden nature of matter, energy,
space and time. That said, when BNL joined QuarkNet in year
2000, we had little idea of what we were getting into.

The Relativistic Heavy Ion Collider at Brookhaven National
Laboratory is a world-class scientific research facility primarily
funded by the U.S. Department of Energy Office of Science. Hundreds
of physicists from around the world use RHIC to study what the
universe may have looked like in the first few moments after its
creation. What physicists learn from these collisions may help us
understand more about why the physical world works the way it does,
from the smallest subatomic particles, to the largest stars.
