Before joining CMS, the Relativistic Heavy Ion Group was a member of the PHOBOS collaboration at the RHIC accelerator, a part of Brookhaven National Lab on Long Island, NY. Working with current group member George Stephans, Corey Reed (one of the group’s former graduate students now an Associate Project Scientist at the university of California at Irvine) has just completed a new publication using PHOBOS data. The analysis used forward calorimeters to “tag” the subset of deuteron+gold collisions in which only the proton or neutron in the deuteron interacted with the gold nucleus. This is currently the only way to study proton+gold collisions at RHIC energies and the only way to study neutron+gold collisions at any highly relativistic energy. The arXiv version of the paper can be found here.
