Recent experimental particle physics results are challenging theoretical preconceptions about physics beyond the Standard Model (BSM). The discovery of a light Higgs boson at the LHC without discovering accompanying BSM physics challenges our notions of naturalness. Similarly, the failure to observe dark matter particles in direct detection experiments like CDMS, LUX, XENON and PandaX challenges our notions of a WIMP “miracle”. One approach that might resolve both of these theoretical challenges would be to assume the new BSM particles are composites in a new, strongly-coupled BSM sector. Searching for strongly-coupled solutions is difficult because of the enormous computational cost of the general approach, lattice field theory, but the current unsatisfactory state of BSM physics encourages us to try anyway. I will summarize the current state of composite Higgs and dark matter studies, focusing particular attention on the work of the Lattice Strong Dynamics (LSD) collaboration.
