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…
The large- limit of the topological susceptibility of Yang-Mills theories via Parallel Tempering on Boundary Conditions
Claudio Bonanno
I present a large- determination of the topological susceptibility of Yang--Mills theories using non-perturbative numerical Monte Carlo simulations of the l…
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…
