We analyze the annihilation cross section of dark matter which interacts with
the standard model sector over the scalar unparticle propagator. We observe
that the annihilation cross section of dark matter pair is sensitive to the
dark matter mass and the scaling dimension of scalar unparticle. We estimate a
range for the dark matter mass and the scaling dimension of scalar unparticle
by using the current dark matter abundance.Comment: 9 pages, 4 figure
