Many extensions of the Standard Model predict new, relatively light pseudoscalars with Higgs-like couplings to Standard Model fermions. Such pseudoscalars can mediate dark matter pair annihilation into Standard Model final states and give rise to significant indirect detection signals. Simple models of this type can explain the GeV Galactic Center excess as observed by the Fermi Large Area Telescope, for example. In this talk, I will discuss the prospects for observing these light states at the LHC through their couplings to Standard Model fermions. While existing searches effectively probe heavy (>90 GeV) pseudoscalars, the 13 TeV LHC could cover much of the interesting parameter space for lower masses in which the new state can have appreciable Yukawa-like couplings but would have escaped detection by LEP and other experiments. The searches I discuss apply generally to new physics scenarios featuring light pseudoscalars with significant couplings to Standard Model quarks and leptons.
