The recently approved Electron-Ion Collider (EIC) will provide a unique new opportunity for searches of charged lepton flavor violation (CLFV) and other new physics scenarios. In contrast to the e & LRARR; & mu; CLFV transition for which very stringent limits exist, there is still a relatively large discovery space for the e & RARR; z CLFV transition, potentially to be explored by the EIC.

With the latest detector design of ECCE (EIC Comprehensive Chromodynamics Experiment) and projected integral luminosity of the EIC, we find the z-leptons created in the DIS process ep & RARR; zX are expected to be identified with high efficiency. A first ECCE simulation study, restricted to the 3-prong z-decay mode and with limited statistics for the Standard Model backgrounds, estimates that the EIC will be able to improve the current exclusion limit on e & RARR; z CLFV by an order of magnitude.

The very high vertex resolution of the ECCE detector configuration plays a critical role in z identification.
