Matching Lagrangian and Hamiltonian Simulations in (2+1)-dimensional U(1) Gauge Theory
C. F. Groß, S. Romiti, L. Funcke +4
At finite lattice spacing, Lagrangian and Hamiltonian predictions differ due to discretization effects. In the Hamiltonian limit, i.e. at vanishing temporal lattice spacing ,…

Isovector axial and pseudoscalar form factors from twisted mass lattice QCD at the physical point
Constantia Alexandrou, Simone Bacchio, Martha Constantinou +6
We present the isovector axial, induced pseudoscalar, and pseudoscalar form factors of the nucleon using three twisted-mass fermion ensembles with degenerate up- and down-, strange…

Strange and charm quark contributions to the muon anomalous magnetic moment in lattice QCD with twisted-mass fermions
C. Alexandrou, S. Bacchio, A. De Santis +15
We present a lattice calculation of the Hadronic Vacuum Polarization (HVP) contribution of the strange and charm quarks to the anomalous magnetic moment of the muon in isospin symm…
