Description
We study the radiative decay modes of a TeV scale top partner that decays to SM top plus either photon or gluon. Such decay modes can be dominant especially in the case where the mixing between the top partner and the SM top goes to zero. The top partner is introduced as a color triplet and electroweak singlet. We take a model-independent approach by introducing an effective dimension-five operator to describe the interaction between the top partner and the SM top. We study the pair production of the top partner and investigate its signal sensitivity in the semileptonic channel at the LHC. We use top tagging technique to identify heavy objects and reduce the background. We then present our results in terms of luminosity curves and branching ratio by changing the top partner mass.
