Quantum corrections to the spin-independent cross section in the inert Higgs doublet model
Abstract
The inert Higgs doublet model is an extension of the standard model with an extra scalar doublet. The extra doublet is Z2 odd while all the other particles are Z2 even, thus the model contains a dark matter candidate. It is known that the spin-independent cross section of the dark matter and the nucleon is highly suppressed for m DM mh/2 at the tree level. In this talk, we show the loop corrections give the significant effects in this regime.
