Indirect search for color octet electron at next-generation linear colliders

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(e8) =1.75TeV and 1.70 TeV at ILC and CLIC with root s=0.5TeV, respectively. CLIC with root s=3TeV will be sensitive upto M(e8) =6.88 TeV. Copyright (C) EPLA, 2011
