A Delphes card for the EIC yellow-report detector

Abstract

The Electron-Ion Collider (EIC) Yellow Report specified parameters for the general-purpose detector that can deliver the scientific goals delineated by the EIC White Paper and NAS report. These parameters dictate the tracking momentum resolution, secondary-vertex resolutions, calorimeter energy resolutions, as well as $\pi/K/p$ ID. We have incorporated these parameters into a configuration card for Delphes, which is a widely used "C++ framework, for performing a fast multipurpose detector response simulation". We include both the 1.5 T and 3.0 T scenarios. We also show the expected performance for high-level quantities such as jets, missing transverse energy, charm tagging, and others. These parametrizations can be easily updated with more refined Geant4 studies, which provides an efficient way to perform simulations to benchmark a variety of observables using state-of-the art event generators such as Pythia8.
