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…
Scale setting of Yang-Mills theories via Twisted Gradient Flow
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…
