Operator Learning in Lattice QCD: Spectral Reconstruction
Alessandro De Santis
In this work, we propose a novel supervised machine-learning-based strategy for extracting smeared spectral functions from Euclidean correlation functions. The strategy revisits th…
Inclusive decays from lattice QCD: computational strategy and a first physical result
Alessandro De Santis, Antonio Evangelista, Gael Finauri +16
We present a strategy to compute the inclusive decay rate for the process from first principles in lattice QCD. The physical decay rate i…
Electromagnetic pion mass splitting using a Pauli-Villars-regulated photon propagator
Alessandro De Santis, Dominik Erb, Harvey B. Meyer
We present a lattice QCD calculation of the charged-neutral pion mass splitting at using a recently proposed framework based on…
Thin single-crystal perovskite detector for high-energy charged particles
Z. Chubinidze, M. Auf der Maur, F. Matteocci +9
The organometal halide perovskites (OMHP) semi-conductors have shown recently a strong potential as radiation detectors, beside the well-known success in photovoltaics and as photo…
First-principle evaluation of inclusive hadronic decays in QCD+QED
Matteo Di Carlo, Simone Bacchio, Erik Bäske +12
We present a strategy to extend lattice calculations of inclusive hadronic decays from isosymmetric QCD to QCD+QED. The inclusive decay rate can be related to suitable Euclide…
The smeared -ratio in isoQCD from first-principles lattice simulations
Francesca Margari, Simone Bacchio, Alessandro De Santis +6
The -ratio is a phenomenological observable of great relevance, both in itself and in applications such as the dispersive approach to the muon anomalous magnetic moment. It can…
