Abstract

We summarize in this letter the implications of the LHC Higgs searches for Higgs-portal models of dark matter for a 125 GeV Higgs. Their impact on the cosmological relic density and on the direct detection rates are studied in the context of generic scalar, vector and fermionic thermal dark matter particles. Assuming a sufficiently small invisi ble Higgs decay branching ratio, we find that current data, in particular from the XENON experime nt, essentially exclude fermionic dark matter as well as light, i.e. with masses below � 60 GeV, scalar and vector dark matter particles.
