Abstract
In particle physics, invariant mass and transverse momentum are key to analyzing collision data from the Compact Muon Solenoid (CMS) experiment. Using CMS data from 2016 and 2017, we created distributions of invariant mass and transverse momentum (pT). Invariant mass distributions are important to set limits on the energy scale Λ for nonresonant searches, and pT is used to study the kinematics of the collision events. Invariant mass distributions are broken up into different mass bins (ranges). PYTHIA, a Monte-Carlo generator, was used to generate sample events for the four different mass ranges of 300, 800, 1300, and 2000 GeV/c^2. These mass ranges were then scaled by their cross sections, with regard to luminosity, and combined into a single histogram. The results of this study of invariant mass and pT provide an important foundation for the rest of the analysis.
