An update on the determination of the sphaleron rate in finite temperature QCD
Nicolò Bellini, Claudio Bonanno, Francesco D'Angelo +3
The sphaleron rate is a key phenomenological quantity both for the axion thermal production in the Early Universe and the Chiral Magnetic Effect occurring in the Quark-Gluon Plasma…

The twisted gradient flow strong coupling without topological freezing
Claudio Bonanno, Jorge Luis Dasilva Golán, Massimo D'Elia +2
We investigate the role of topology on the lattice determination of the strong coupling renormalized via gradient flow. To deal with the topological freezing of st…
