  We study the contribution of the antisymmetric tensor unparticle mediation to
the diphoton production rate of the Higgs boson and try to explain the
discrepancy between the measured value of the decay width of the discovered new
resonance and that of the standard model Higgs boson. We observe that tree
level contribution of the antisymmetric unparticle mediation is a possible
candidate to explain the measured value of the diphoton decay rate.
