| Abstract | MEASUREMENT OF POLARIZED PROTON PROTON ELASTIC SCATTERING AT THE RELATIVISTIC HEAVY ION COLLIDER (RHIC) Ivan Koralt Old Dominion University, 2013 Director: Dr. Stephen Biiltmann Elastic proton-proton (pp) scattering is one of the most fundamental processes in nature and yet, it is one of the most difficult to describe. There are two interactions involved in this process: electromagnetic (Coulomb) and hadronic (strong) interactions. Underlying exchange mechanisms of these two interactions are the virtual photon and the Pomeron exchange, respectively. The difficulty of elastic pp scattering arises from the fact th a t the nature of the Pomeron and its exchange are not well understood and need a theoretical approach, which is still under development. At the Relativistic Heavy Ion Collider (RHIC) a t Brookhaven National Lab (BNL) we are studying the hadronic interaction via the dynamics of high-energy pp collisions using the Solenoidal Tracker At RHIC (STAR) detector. The “Physics W ith Tagged Forward Protons At STAR” experiment, formerly known as the “pp2pp” experiment, is a part of STAR and it successfully conducted measurements of elastic scattering observables by the use of its forward particle detectors, known as Roman pots. In this dissertation I present the measurement of polarized pp elastic scattering a t RHIC. I describe the app2pp a t STAR” experiment focusing on elastic scattering observables from the data taken in Run9. I report the result of the experimental slope param eter B of the diffractive peak of the elastic cross-section at the center-of-mass energy y/s = 200 GeV in the four-momentum transfer squared t range 0.006 < |t| < 0.02 (G eV/c)2. I also present d a ta analysis techniques and Monte Carlo simulations developed for the analysis and improvement of the detector performance, correction of the recorded experimental data and an estim ate of systematic errors of this measurement.
