FI: PHENOMENOLOGY OF THE QCD AXION 
 ELENCO COMPLETO 

DATA: 19-07-2017

SEZIONE DI FIRENZE
Seminario teorico del mercoledi' di Giovanni Villadoro (ICTP, Trieste) Abstract: The QCD axion is probably the most robust solution to the strong CP problem and a natural dark matter candidate. While its properties, such as the mass and the couplings, are mostly determined by non-perturbative QCD effects I will present recent computations demonstrating that they can be reliably extracted with percent accuracy, which is important for the theory interpretation of experimental results. I will also discuss some recent lattice QCD results highlighting a departure from the usual instanton estimates and potentially changing the prediction for the axion relic abundance substantially.
