Spectroscopy is a fundamental matter in lattice gauge theories. In this talk, I will inspect a new technique used to perform finite volume spectroscopy, i.e. fitting spectral densities. This will be shown, giving an overview of how I give estimation of such spectral density, and how I fit it, using a mixed representation ($N_{\rm f} = 2$ fundamental fermions and $N_{\rm as} = 3$ 2-index...

Restricted Boltzmann Machines (RBMs) are energy-based machine learning models inspired by the spin-glass system. Using its energy function, we can analyse its training dynamics in terms of statistical mechanics and map its hyperparameters to thermodynamic quantities. This interpretability unravels the black-box nature of the machine-learning process and allows us to understand the underlying...

With perturbative QCD unable to explain the phenomenon of confinement and predict the spectrum/dynamics of hadrons that comes with it, an alternative framework must be used. Lattice QCD along with the two-particle finite-volume formalism can be used to obtain scattering amplitudes non-perturbatively, whose analytic structure yields information about hadronic resonances.

In this talk, I...
