Abstract

Current models occasionally misinterpret particle charges due to high transverse momentum. To this end, we designed a module that, when implemented, matches generated particles to reconstructed ones and logs the number of incorrect signs in the reconstruction. We further divide these sign flips between high pT and low pT, based off a momentum cut specified in the module. Further, our current model does not account for particle decay events away from the primary vertex, as the module previously created for locating displaced vertex events did not function properly. We fixed previous errors and made the module more reliable and accurate to simulated particle events. We added functionality to test several different cylinder radii to propagate tracks to, making the estimated displaced vertex location more accurate.
