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.

The Quark Matter 2008 conference was held from 4-10 February 2008 at Birla auditorium and convention centre in Jaipur which is about 260 km away from Delhi. The pink city Jaipur is a famous tourist place known for forts, palaces, architectural marvels and tales of valor. It was the twentieth in the series of international conferences on ultra relativistic nucleus-nucleus collisions and was attended by over 400 scientists from all over the world. More...
From PHENIX I
By Achim Franz
More than 20 years ago, at Quark Matter 1987 in Nordkirchen, Germany, the first data from the CERN SPS heavy ion program were presented . At that time the emphasis was on global observables like overall multiplicity, transverse energy flow, or even collision size and shape via HBT interferometry. More...
from PHENIX II: Photons and Leptons
By Terry Awes
The PHENIX experiment at RHIC was designed with emphasis on the measurement of leptons and photons. Photons and leptons are of special interest because they are penetrating probes that do not undergo strong interactions and therefore are unlikely to interact with the dense matter produced in heavy-ion collisions. Thus, they carry information about the system at the time of their production, throughout the entire evolution of the collision. More...
QM08 Highlights I: Characterizing the new state of matter
discovered at RHIC
By Tim Hallman, STAR Collaboration
The discovery phase at RHIC has yielded overwhelming evidence for the creation of a new state of matter in central heavy ion collisions — the hottest and densest yet examined in the laboratory. It is highly opaque to colored probes such as quarks and gluons, but not to photons. Elliptic flow measurements suggest the matter behaves as a relativistic quantum liquid with minimal shear viscosity. More...
QM08 Highlights II: STAR Results on Medium Properties and
Response of the Medium to Energetic Partons
By Bedangadas Mohanty, STAR Collaboration
After the discovery of the phenomenon of jet quenching at RHIC, the focus has been to study the properties of the medium formed in heavy ion collisions at high energy . The basic approach has been to use the highly energetic partons available in the initial stages of the collisions as a probe for the properties of the subsequent medium that is formed. These partons then fragment into jets of hadrons and we look for modification to the properties of these jets. More...
Memoriam: Zeev Fraenkel
By Itzhak Tserruya
Professor Zeev Fraenkel, one of the senior scientists and pioneers of nuclear physics in Israel, died suddenly of pneumonia on 17 February 2008 in Rehovot, Israel, four days after returning from India where he attended the last Quark Matter conference. More...
