Aula D

IFPU, Trieste


The trilateral meetings are a series of one day events designed to strengthen the scientific relations in particle, astroparticle physics and cosmology between Trieste, Nova Gorica and Ljubljana.


The event will take place in room D at the IFPU in Trieste.

      QCD Axion: Some Like It Hot 45m

      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.
