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…
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…
Comparing RM123 and non-perturbative QCD+QED approaches to the HVP with C-periodic boundary conditions
Anian Altherr, Isabel Campos, Alessandro Cotellucci +10
Isospin-breaking corrections to the HVP are among the leading sources of uncertainty in the Standard Model prediction of the muon . In recent work by the RC collabor…
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…
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…
