Abstract
Final State Interactions are the interactions of particles created by previous particle interactions. Simulated Proton Final State Interactions for show large variations from experimental. Final State Interactions are difficult and expensive to examine through experiments, making further research prohibitively resource intensive. If simulated Final State Interactions more closely matched experimental data, more accurate observations may be made. An accurate simulation is vital as some of the resulting particles may be absorbed, preventing observations. Simulations must accurately calculate the cross section, or the area in which the re-interactions occur, as the size of the cross section affects the probability of absorption. Some variations between experiments and the simulation may be attributed to the cross section of the interaction being calculated to be too large, resulting in a smaller distance between the smaller interactions of the Final State Interactions. A correction identified by Pandharipande and Pieper of Argonne was applied to the simulation with the intent to reduce the deviations from the experimental data by limiting the size of the cross section. It was found that the correction made reduced the discrepancy. This small change suggests that other factors may be at work in the experiment that have not yet been identified.
