MC4EIC: Monte Carlo event simulation for the EIC

Due to the COVID-19 virus, the MC4EIC workshop is being held online using Zoom. 

We have taken live notes during the meeting, which will form the basis for a workshop report. This document will inform future discussions and become part of the Snowmass community planning process. The live notes are available as a Google document, anyone can edit the live notes directly.

The MC4EIC workshop has been organized by the CTEQ collaboration and the EIC User Group and has been hosted by CFNS as a remote meeting from November 18-19. 

Success of the EIC science program critically depends on precise theoretical predictions for electron-ion collisions. Parton showering programs serve as a backbone for such calculations in most particle physics experiments, and the EIC is no exception. Developing precision simulations will therefore be mandatory. It will require advancements in QCD theory and computational methods, as well as a close dialog between experimentalists and theorists.

To facilitate this dialog, we have brought together experts in various domains of QCD theory and experiment to discuss recent advances in the development of event generators, as well as needs and requirements for future progress. 

This MC4EIC kick-off workshop will establish a foundation for an in-depth look at the MC event generators that are currently used or developed for the EIC. Questions that will be defined at the kick-off workshop will be addressed at the next workshop, tentatively to be held in Spring 2022. 

MC4EIC is part of the CFNS workshop/ad-hoc meeting series.
