Abstract

In this work the flavor-changing, rare t -> cgg decay induced by mediation of scalar and tensor unparticles is studied. Using the standard model result for the branching ratio of the t -> cgg decay, the parameter space of d(U) and Lambda(U), where the branching ratio of this decay exceeds the one predicted by the standard model, is obtained. Measurement of the branching ratio larger than 10(-9) can give valuable information for establishing unparticle physics.
