Sommaire:

We consider a composite model where both the Higgs and a complex scalar \chi, which is the dark matter (DM) candidate, arise as light pseudo Nambu-Goldstone bosons from a strongly coupled sector with TeV scale confinement. The global symmetry structure is SO(7)/SO(6), and the DM is charged under an exact U(1) \subset SO(6) that ensures its stability. The DM phenomenology depends strongly on whether the \chi shift symmetry is broken or respected by the coupling of the top quark to the strong sector. I will discuss both possibilities in detail, including the interplay with LHC physics. Based on arXiv:1707.07685 and work in progress.
