Measurements of the cosmic microwave background (CMB) have been fundamental in establishing the cosmological standard model, ΛCDM, which describes the evolution of the universe from the earliest moments to the present day. Upcoming measurements with increasingly powerful cameras are now poised to search for physics beyond the standard model, including new particles that could leave an imprint in the pattern of the CMB. I will review the physics we can learn from these new CMB surveys and present the upcoming CMB-S4 project to which Fermilab is a major contributor.
