We present a proof-of-concept numerical study of the real-time topological rate at non-zero momentum in quenched lattice QCD at a temperature MeV,…
Topological Susceptibility and QCD at Finite Theta Angle
Claudio Bonanno, Claudio Bonati, Massimo D'Elia
In this chapter we provide a pedagogical introduction to the main theoretical aspects related to topology and -dependence in Quantum Chromo-Dynamics (QCD), and to their phenomen…
Lattice determination of the QCD low-energy constant
Claudio Bonanno, Gilberto Colangelo, Francesco D'Angelo +8
We provide a non-perturbative determination of the scheme- and scale-independent low-energy constant , appearing in the QCD effective chiral Lagrangia…
Scale setting of SU() Yang--Mills theory, topology and large- volume independence
Claudio Bonanno, Jorge Luis Dasilva Golán, Margarita García Pérez +2
We set the scale of SU() Yang--Mills theories for and in the large- limit via gradient flow, as a first step towards the computation of the large- -parameter…
Strong CP problem, theta term and QCD topological properties
Claudio Bonanno, Claudio Bonati, Massimo D'Elia
In this chapter we introduce the -dependence and the topological properties of QCD, features of the strongly interacting sector which give rise to the strong CP problem in the m…

Claudio Bonanno, Jorge Luis Dasilva Golán, Massimo D'Elia +2
We present preliminary results for the scale setting of Yang-Mills theories using twisted boundary conditions and the gradient-flow scale . The end goa…
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…

Giorgio Almirante, Nikita Astrakhantsev, V. V. Braguta +5
We compute the electrical conductivity of the strongly interacting medium in the presence of strong magnetic background fields, , and for different values of the temp…
Non-perturbative determination of the QCD sphaleron rate
Claudio Bonanno, Francesco D'Angelo, Massimo D'Elia +2
The strong sphaleron rate, i.e., the rate of real time QCD topological transitions, is a key phenomenological quantity, playing a fundamental role in several physical contexts. In…

We simulate QCD at the physical point combining open and periodic boundary conditions in a parallel tempering framework, following the original proposal by M. Hasenbusch…
