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.
Cold Nuclear Matter Effects on J/ψ Production
By Ramona Vogt
PHENIX has some very interesting results on the J/ψ nuclear modification factor, RAA, in Au+Au collisions, as nicely described by Tony Frawley in the September 25, 2007 issue of RHIC News. Complicating the interpretation of RAA are the effects of color screening on the J/ψ as well as stronger effects on the higher charmonium resonances, the χcJ and ψ′ states. More...
Beams Change Their Charge
By Spencer Klein
RHIC accelerator physicists inject beams of bare nuclei (with all of their electrons removed) into the accelerator. One might expect that these beams would continue to circulate unchanged. However, every rule has an exception, and, in the 2005 run with copper beams, a team of Brookhaven National Lab, Lawrence Berkeley National Lab and CERN researchers observed that some of these bare nuclei gained electrons, transforming into a beam of single-electron ions.

Starting Up RHIC
By Michael Sivertz
The RHIC Run 08 has started running "Physics", beginning a few day early on 26 November 2007. Although I am the Scheduling Physicist for RHIC this year, I am not an accelerator physicist, so my view of the RHIC Start Up is more from the standpoint of a spectator. More...
In Memoriam: Michael P. Schmidt
Professor Michael P. Schmidt, high energy elementary particle physicist, died on November 18. He was born on January 18, 1954 in Los Angeles, CA., and his family moved to San Jose, CA where he attended public schools. He graduated from The University of California, Berkeley in 1975 with a B.S. degree with Highest Honors and Great Distinction in General Scholarship. He received his PhD from Yale where he wrote his dissertation on CP violation in K meson decays. More...
