Abstract

Singlet scalar dark matter can naturally arise in composite Higgs models as an additional stable pseudo-Nambu-Goldstone boson. We study the properties of such a candidate in a model based on SU(6)/SO(6), with the light quark masses generated by 4-fermion interactions. The presence of nonlinearities in the couplings allows us to saturate the relic density for masses 400<mDM<1000GeV, and survive the bound from direct detection and indirect detection. The viable parameter regions are in reach of the sensitivities of future upgrades, like XENONnT and LZ.
