Spectral densities from Euclidean correlators via integral transforms: theoretical framework
Leonardo Giusti, Matteo Saccardi, Diego Toniolo
Spectral densities link experimental measurements to dynamical properties of a quantum field theory which, in turn, can be resolved non-perturbatively from the Euclidean time-depen…
Spectral densities from Euclidean-time lattice correlation functions
Matteo Saccardi, Mattia Bruno, Leonardo Giusti
In quantum field theories, spectral densities are directly related to relevant physical observables. In Lattice QCD, their non-perturbative extraction from first principles require…
On the color structure of Yang-Mills theory with static sources in a periodic box
L. Giusti, A. L. Guerrieri, S. Petrarca +2
We present an exploratory numerical study on the lattice of the color structure of the wave functionals of the SU(3) Yang-Mills theory in the presence of a static pair. I…
Low-energy couplings of QCD from topological zero-mode wave functions
L. Giusti, P. Hernandez, M. Laine +2
By matching 1/m^2 divergences in finite-volume two-point correlation functions of the scalar or pseudoscalar densities with those obtained in chiral perturbation theory, we derive…
B_K from quenched overlap QCD
N. Garron, L. Giusti, C. Hoelbling +2
We present an exploratory calculation of the standard model Delta S=2 matrix element relevant for indirect CP violation in K -> pi pi decays. The computation is performed with over…
Numerical techniques for lattice QCD in the --regime
L. Giusti, C. Hoelbling, M. Lüscher +1
In lattice QCD it is possible, in principle, to determine the parameters in the effective chiral lagrangian (including weak interaction couplings) by performing numerical simulatio…
