Scalar field dark matter, cross section and Planckscale physics
Abstract
In recent papers we have proposed that the dark matter of the Universe could be from scalar field origin. In this Letter, we find that if the scale of renormalization of the model is of order of the Planck mass, then a scalar field Φ endowed with the scalar potential V=V_{0}[cosh(λ√κ_{0}Φ)1] can be a reliable model for dark matter in galaxies. The predicted scattering cross section fits the value required for selfinteracting dark matter.
