Abstract
At RHIC (Relativistic Heavy Ion Collider), two atomic nuclei are stripped of their surrounding electrons and accelerated to near the speed of light. Creighton is a member of the STAR (Solenoidal Tracker At RHIC) collaboration that studies ultraperipheral collisions through the STAR detector. Ultraperipheral collisions occur when two nuclei miss but pass each other at a very short distance yet still interact with one another electromagnetically. While the nuclei continue along the beam line, particles are produced from the interaction. The electric fields in these interactions are very intense. Studying electron-positron pairs can aid in understanding the quantum electrodynamics in these intense fields. This talk will introduce the use of different particle identification methods used for electron-positron pairs produced during such interactions.
