Contribution

It demonstrates the superior mass reach and probing capabilities of e-FCC colliders for color octet electrons compared to existing and planned colliders.

Findings

e-FCC covers wider e_{8} mass range than LHC.

e-FCC with high electron energy surpasses FCC pp collider in e_{8} search.

e-FCC can probe compositeness scales up to hundreds of TeV.

Abstract

Resonant production of color octet electron, e_{8}, at the FCC based ep colliders has been analyzed. It is shown that e-FCC will cover much a wider region of e_{8} masses compared to the LHC. Moreover, with highest electron beam energy, e_{8} search potential of the e-FCC exceeds that of FCC pp collider. If e_{8} is discovered earlier by the FCC pp collider, e-FCC will give opportunity to handle very important additional information. For example, compositeness scale can be probed up to hundreds TeV region.
