Topological Susceptibility and QCD Axion Mass: QED and NNLO corrections
Marco Gorghetto, Giovanni Villadoro
We improve the precision of the topological susceptibility of QCD, and therefore of the QCD axion mass, by including and NNLO corrections in the chiral expansion, w…

Axions from Strings: the Attractive Solution
Marco Gorghetto, Edward Hardy, Giovanni Villadoro
We study the system of axion strings that forms in the early Universe if the Peccei-Quinn symmetry is restored after inflation. Using numerical simulations, we establish the existe…
