Description
Residual annihilation of sub-GeV mass thermal relic dark matter candidates during big bang nucleosynthesis (BBN) can impact its predictions of light element abundances. Focusing on candidates with velocity-suppressed annihilation channels, I will discuss how the hadronic injection of pions and kaons beyond freeze-out, and their subsequent interaction with protons and neutrons prior to the deuterium bottleneck, provides a sensitivity to annihilation that surpasses that of the cosmic microwave background (CMB) and indirect detection in the galaxy.
