Abstract
The existence of dark matter has been accepted for the last half century, yet despite clear astrophysical evidence, nothing indicative has been seen in particle accelerators. Many prevalent theories of dark matter predict a dark sector of particles, analogous to the Standard Model. A massive dark photon of a dark sector model could serve as a portal between this hidden sector and our own. Thus our group is conducting an exotic massive dark photon search, which has a distinctive dilepton jet signature. Recently, however, we have noticed a discrepancy between our Monte Carlo and data in low mass regions of our validation plots. After a preliminary investigation, we found a significant number of potential background events in an unaccounted for low mass Drell-Yan channel. It is therefore in our current interest to study fake lepton jet production from the Drell-Yan process with an invariant mass in the low GeV/c2 range. Thus, this project aims to present a Monte Carlo study of Drell-Yan dilepton production.
