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…
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…
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…
Chiral condensate from the spectrum of the staggered Dirac operator
Claudio Bonanno, Francesco D'Angelo, Massimo D'Elia
The chiral condensate is computed from the mode number of the staggered Dirac operator. This result is compared with those obtained with other approaches, based on the quark mass d…
Sphaleron rate as an inverse problem: a novel lattice approach
Claudio Bonanno, Francesco D'Angelo, Massimo D'Elia +2
We compute the sphaleron rate on the lattice. We adopt a novel strategy based on the extraction of the spectral density via a modified version of the Backus-Gilbert method from fin…
Sphaleron rate from lattice QCD
Claudio Bonanno, Francesco D'Angelo, Massimo D'Elia +2
We compute the sphaleron rate on the lattice from the inversion of the Euclidean time correlators of the topological charge density, performing also controlled continuum and zero-s…
The chiral condensate of QCD from the spectrum of the staggered Dirac operator
Claudio Bonanno, Francesco D'Angelo, Massimo D'Elia
We compute the chiral condensate of QCD from the mode number of the staggered Dirac operator, performing controlled extrapolations to both the continuum and the chiral limit.…
Sphaleron rate of QCD
Claudio Bonanno, Francesco D'Angelo, Massimo D'Elia +2
We compute the sphaleron rate of QCD at the physical point for a range of temperatures MeV MeV. We adopt a strategy recently applied in th…
Sphaleron rate from a modified Backus-Gilbert inversion method
Claudio Bonanno, Francesco D'Angelo, Massimo D'Elia +2
We compute the sphaleron rate in quenched QCD for a temperature from the inversion of the Euclidean lattice time correlator of the topological charge density. W…
The QCD topological susceptibility at high temperatures via staggered fermions spectral projectors
Andreas Athenodorou, Claudio Bonanno, Claudio Bonati +7
The QCD topological observables are essential inputs to obtain theoretical predictions about axion phenomenology, which are of utmost importance for current and future experimental…
Topological susceptibility of QCD from staggered fermions spectral projectors at high temperatures
Andreas Athenodorou, Claudio Bonanno, Claudio Bonati +7
We compute the topological susceptibility of QCD with physical quark masses in the high-temperature phase, using numerical simulations of the theory discretized on a spac…
