dc.descriptionWe study the possible annihilation cross section of scalar dark matter and its coupling λ_D to the standard model Higgs in the case of the electroweak symmetry breaking driven by unparticle. Here the annihilation process occurs with the help of three intermediate scalars which appear after the mixing. By respecting the annihilation rate which is compatible with the current relic density we predict the tree level coupling λ_D. We observe that the unparticle scaling d_u plays a considerable role on the annihilation process and, therefore, on the coupling λ_D.
