Abstract: (Elsevier)

In this work we study the flavor changing neutral current (FCNC) decays of the top quark, t→cγ and t→cg , in the framework of the unparticle physics. The Standard Model predictions for the branching ratios of these decays are about ∼5×10−14 , and ∼1×10−12 , respectively. The parameter space of λ , Λ , and d is obtained by taking into account the SM predictions and the results of the simulation performed by the ATLAS Collaboration for the branching ratios of t→cγ and t→cg decays.
