5 WIMP Dark matter DM DM DM DM DM DM DM DM DM DM DM DM
6 Why is it stable? A possible answer: composite dark matter Some composites states may be accidentally stable. In the standard model QCD, Baryon Charged pion (if EW scale is large) Dark matter from a new QCD-like theory?
7 Bonus: Mass scale m DM < 100 TeV M Pl Confinement g 2 (E) generates a WIMP scale E
8 Features of our model A simple setup with chiral gauge symmetry (Strong coupling is vector-like) Constituent quark mass is forbidden, and the dynamical scale is the unique mass scale High predictability, but I cannot calculate observables Lattice information is crucial

18 Abundance of baryon baryons mesons v = 4 m B 2 exp( N) large N behavior (Witten, 1980) smaller DM mass may be OK Important for other scenario, including Composite Higgs Lattice? Probably difficult, but interesting
