Performance of Low Mode Averaging on Twisted-Mass Fermion Ensembles at the physical pion mass point
Constantia Alexandrou, Simone Bacchio, Antonio Evangelista +4
We study the performance of low-mode averaging (LMA) on twisted-mass fermion ensembles at near-physical quark masses, assessing both its theoretical framework and practical cost-ef…
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 Euclidea…
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…
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…
Lattice QCD study of the decay
D. Bečirević, R. Di Palma, R. Frezzotti +4
We present the results of our lattice QCD computation of the electric () and magnetic form factors relevant to the decay by using the gauge fiel…
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…
Inclusive semileptonic decays of the meson: A first-principles lattice QCD calculation
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 usin…
Smeared -ratio in isospin symmetric QCD with Low Mode Averaging
Simone Bacchio, Alessandro De Santis, Antonio Evangelista +8
Low Mode Average (LMA) is a technique to improve the quality of the signal-to-noise ratio in the long time separation of Euclidean correlation functions. We report on its beneficia…
Valence leading isospin breaking contributions to
Simone Bacchio, Antonio Evangelista, Roberto Frezzotti +6
By employing the RM123 approach to QCD+QED, we computed the valence quark-connected isospin-breaking corrections to the light, strange and charm contributions at leading order in $…
