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…
Emergence of the Resonance from Lattice QCD
Haobo Yan, Maxim Mai, Marco Garofalo +6
The mass of the lightest hadron in nature, the pion, is one seventh of that of the nucleon and one tenth of the mass of its first excited state, the . This enormous energ…
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…
An update on the HVP contribution to in isoQCD from ETMC
Simone Bacchio, Alessandro De Santis, Antonio Evangelista +7
We present an update on the determination of the leading-order hadronic vacuum polarisation contribution to the muon anomalous magnetic moment in isospin-symmetric QCD by the Exten…
A Comprehensive Stress Test of Truncated Hilbert Space Bases against Green's function Monte Carlo in U(1) Lattice Gauge Theory
Timo Jakobs, Marco Garofalo, Tobias Hartung +5
A representation of Lattice Gauge Theories (LGT) suitable for simulations with tensor network state methods or with quantum computers requires a truncation of the Hilbert space to…
Inclusive semileptonic decays of the meson: Lattice QCD confronts experiments
Alessandro De Santis, Antonio Evangelista, Roberto Frezzotti +13
We present the results of a first-principles theoretical study of the inclusive semileptonic decays of the meson. We performed a state-of-the-art lattice QCD calculation by…
