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.

Measurement of Run05 Proton Beam Polarization by Itaru
Nakagawa
RHIC spin program has been studying the decomposition of nucleon
spin in terms of the contributions from its constituents -
quarks and gluons - using various observed asymmetries through
polarized proton-proton collision process. All these asymmetry
studies requires the knowledge of the beam polarization in order
to interpret observed asymmetry with the spin structure of
nucleon. Therefore the measurement of the beam polarization is a
critical path.

The
NASA Space Radiation Facility at BNL By Michael Sivertz
So you want to be an astronaut? Space flight can be dangerous,
but not all dangers come in the form of large hungry aliens with
a bad attitude. NASA is concerned about the amount of radiation
that astronauts are exposed to in routine space flights.
Radiation from cosmic rays can represent a significant risk to
astronauts, depending on the duration of the flight and other
factors.

Ring Electric Dipole Moments: The Case for a Deuteron EDM By
Yannis Semertzidis
Even though the possession of a non-zero value of a magnetic
dipole moment (MDM) by a fundamental particle is common place
there is not a single case observed so far for the possession of
an electric dipole moment (EDM). Such an observation would have
a profound implication about our understanding of the universe
because it would point to a new, large source of CP-violation
(the combined charge (C) and parity (mirror reflection, P)
symmetries); much bigger than what is allowed by the standard
model (SM).

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.
