Analyzing High Energy Physics data with Rivet and comparing to Monte Carlo models

The Quark Gluon Plasma (QGP) is a phase of matter created in extremely high energy collisions of nuclei in particles accelerators such as the Large Hadron Collider (LHC) in Switzerland or the Relativistic Heavy Ion Collider (RHIC) in New York. We can compare data with Monte Carlo models using the Robust Independent Validation of Experimental and Theory program (Rivet). In particular, we often examine the production of charged particles in heavy ion collisions to gain deeper understanding of the properties of the QGP. A Rivet analysis is implemented for identified particle yields and particle ratios in gold-gold collisions and is used to make comparisons of data and PYTHIA Angantyr.
