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.
Search at RHIC
By J. Sandweiss
Strange Quark Matter (SQM) are hypothesized to be nuclei which consist of a single "bag" of up (u), down (d) and strange (s) quarks. This is in contrast with ordinary nuclei which are composed of nucleons i.e. groups of three quarks (two up, one down for protons and two down, one up for neutrons). The existence of stable SQM was predicted by Witten in 1984. For a variety of reasons, it has not been possible to prove or to disprove this hypothesis. Recently an experiment with STAR at RHIC has added to this situation by searching for SQM produced in 200 GeV Au-Au collisions. None were found but limits were set using an ingenious experimental approach. More...
Belikov of PHENIX
Sergey Belikov died early on the morning of October 22, 2007 after living with cancer for six years. Sergey was a physicist in the Physics Department at Brookhaven National Laboratory, and a member of PHENIX collaboration. He was expert in many parts of the PHENIX experiment, and worked on some of the key parts of the experiment from the Run Control program that runs the experiment, to the digitizers used in the electromagnetic calorimeter and muon tracker, but to those who worked with him, their memory is of a colleague who was always helpful, always willing to share what he knew, and never satisfied until he found a clean solution to a difficult problem.

More Students Complete Ph.Ds on RHIC Experiments
Three more Ph.D.s were granted for work on RHIC experiments (These are in addition to those announced earlier this year in the September 25 issue of RHIC News). They are: Yuting Bai, Jonathan Bouchet, and Mate Csanad. More...
The Daya Bay Experiment
By Steve Kettell
BNL is one of the host labs for US participation in the Daya Bay experiment which will provide the most precise measurement of last unobserved neutrino mixing angle, θ13, with an expected sensitivity to sin22θ13 of better than 0.01 at 90% CL after three years of operation. This is an exciting opportunity to study physics beyond the Standard Model. The existence of neutrino oscillations requires an extension of the Standard Model and raises several interesting questions: why neutrinos have mass and why they are so small (more than 12 orders of magnitude smaller than the top quark)? why two of the mixing angle are large and one is small? and can neutrino CP violation explain the matter anti-matter asymmetry in the universe?
