1202.2673 (Takehiro Nabeshima)

Higgs portal dark matter at a linear collider    [PDF]

Takehiro Nabeshima
We investigate the possibility of detecting dark matter at TeV scale linear
colliders in the scenario where the dark matter interacts with standard model
particles only via the Higgs boson. In this scenario, the dark matter would be
difficult to be tested at the LHC especially when the decay of the Higgs boson
into a dark matter pair is not kinematically allowed. In this talk, we discuss
whether even such a case can be explored or not at the ILC and CLIC via the Z
boson fusion process. This talk is mainly based on Phys. Rev. D 82, 055026
(2010) and Phys. Lett. B 701, 591 (2011).
