2:30 PM → 3:15 PM QCD Axion: Some Like It Hot

The QCD axion is one of the most compelling targets for physics beyond the Standard Model, offering a characteristic imprint in the Early Universe as a hot relic. In this talk we derive a state-of-the-art bound on the QCD axion from Cosmology by confronting momentum-dependent Boltzmann equations against up-to-date measurements of the CMB – including ground-based telescopes – and abundances from BBN. We conclude presenting forecasts using dedicated likelihoods for future cosmological surveys, and exploiting recent results on non-perturbative thermal rates at the crossover from lattice QCD.

Speaker: Mauro Valli (Istituto Nazionale di Fisica Nucleare)
