The hadronic-vacuum-polarization contribution to the muon anomalous magnetic moment in isospin-symmetric lattice QCD with twisted-mass fermions
C. Alexandrou, S. Bacchio, A. De Santis +18
We present a lattice-QCD calculation of the leading-order hadronic-vacuum-polarization (HVP) contribution to the anomalous magnetic moment of the muon in isospin-symmetric QCD. We…
Measuring Mass Splittings in Baryon SU(2) Multiplets
Constantia Alexandrou, Simone Bacchio, Antonio Evangelista +2
The inclusion of isospin-breaking corrections arising from electromagnetic interactions and the up-down quark mass difference is becoming increasingly important in lattice QCD calc…
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…
Probing and graph coloring techniques for trace estimation in Lattice QCD
Mario Papace, Andreas Frommer, Jose Jimenez-Merchan +3
The computation of , where is the Wilson-Dirac matrix of Lattice QCD, is a fundamental and computationally demanding task with applications to disconnected…
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…
