Monte Carlo-Data validation for Electron Ion Collider Group

Abstract

The upcoming Electron Ion collider facility is aimed at providing more information on the structure inside the hadrons. As part of improving the detector development and integra- tion of software into the main workflow of data analysis and prediction. Modern day general purpose generators like Herwig7 and Pythia8 are tested using data validation against Deep Inelastic Scattering data from HERA. Data for DIS was taken and compared in a com- prehensible manner using rivet tool which is excellent for data comparison and generator validation. Overall performance of the generators are slightly inconsistent to be considered as more accurate than the other, for the list of experiments considered, The specific areas where the generators are more reliable than the other is given in the summary chapter. The possible reasons for the failure of a particular generator to reproduce the data properly in certain regions are also hypothesized. The results provide a useful input to the software working group of EIC when it comes to making decisions on integrating the software to workflow and use for data prediction and detector development.
