Abstract
The EIC Comprehensive Chromodynamics Experiment (ECCE) detector has been recommended as a reference
design for the proposed Electron-Ion Collider (EIC) program. This paper presents simulation studies of exclusive
J/๐ detection and selected physics impact results in EIC using the projected ECCE detector concept. Exclusive
quarkonium photoproduction is one of the most popular processes in EIC, which has a large cross section
and a simple final state. Due to the gluonic nature of the exchange Pomeron, this process can be related to
the gluon distributions in the nucleus. Preliminary results estimate the excellent statistics benefited from the
large cross section of J/๐ photoproduction and superior performance of ECCE detector concept. The precise
measurement of exclusive J/๐ photoproduction at EIC will help us to more deeply understand nuclear gluon
distributions, near threshold production mechanism and nucleon mass structure.
