Measuring Anti-Nuclei at RHIC Using the STAR Detector
Abstract
High energy nucleus-nucleus collisions at RHIC will lead to copious production of anti-nucleons since the energy of the colliding system is well above the threshold for anti-nucleon production. These anti-nucleons should coalesce into clusters of light anti-nuclei. In some sense, RHIC will be the first anti-nuclei factory. Simple arguments suggest that so far unseen anti-nuclei should be produced at RHIC, including ^4barHe and perhaps ^6barLi. It will, however, be a great experimental challenge to identify these anti-nuclear states. STAR should be capable of observing light anti-nuclei using a combination of dE/dx and momentum measurements from the STAR TPC. The expected performance of the STAR detector for such measurements and expected backgrounds will be discussed.
