Comparing measurements of jets to JETSCAPE predictions

At the Large Hadron Collider and the Relativistic Heavy Ion Collider, heavy ions are collided at ultrarelativistic speeds to create what is known as a quark-gluon plasma. At sufficiently high temperatures and energy densities, quarks and gluons become asymptotically free, and are no longer confined inside of individual nucleons. Monte Carlo simulations are used to better understand how the QGP interacts and cools. These can be compared to detector data to see how well a given predictive theory matches experiment. The JETSCAPE collaboration allows for the combination of multiple models in one software package in an attempt to create a single monte carlo that accurately predicts the event. Each JETSCAPE Monte Carlo can be analyzed in the RIVET analysis framework, which allows testing by different methods provided in its library. One example is a CMS measurement of inclusive jet cross sections in proton-proton and lead-lead collisions at center of mass energy of 2.76 TeV. This implementation of the CMS jet spectrum measurement in RIVET was tested on the PYTHIA Angantyr Monte Carlo generator. We will discuss the technical details, outstanding challenges, and future directions for this work.
