Color octet electron search potential of FCC based e-p colliders

摘要

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