TL;DR
This paper explores the potential to detect color octet electrons indirectly at future linear colliders by analyzing gluon production, estimating the mass ranges where these particles could be observed.
Contribution
It presents the first detailed analysis of indirect signatures of color octet electrons at next-generation linear colliders, including signal-background discrimination and sensitivity estimates.
Findings
Color octet electrons could be detected up to 1.75 TeV at ILC.
Detection potential extends to 1.70 TeV at CLIC with 0.5 TeV energy.
At CLIC with 3 TeV, sensitivity reaches 6.88 TeV.
Abstract
In this study we investigated indirect manifestations of color octet electron at the next generation linear colliders: International Linear Collider (ILC) and Compact Linear Collider (CLIC). Namely, production of two gluons via color octet electron exchange is considered. Signal and background analysis have been performed taking into account initial state radiation and beamstrahlung. We show that color octet electron (e_(8)) manifestation will be seen upto M(e_(8))=1.75 TeV and 1.70 TeV at ILC and CLIC with sqrt(s)=0.5 TeV, respectively. CLIC with sqrt(s)=3 TeV will be sensitive upto M(e_(8))=6.88 TeV.
