Higher Mellin Moments of the Unpolarized PDF of the Pion and the Kaon from Lattice QCD
Constantia Alexandrou, Simone Bacchio, Priyajit Jana +6
We present results on the Mellin moments of the unpolarized parton distribution function (PDF) of the pion and kaon up to the fourth order. The computation is done using one $N_f=2…
The origin of excited states of the baryon at the SU(3) point from Lattice QCD
Javier Suarez Sucunza, Thomas Luu, Maxim Mai +3
In this work we determine the finite-volume lattice QCD spectrum at the flavor symmetric point in the meson-baryon singlet and octet irreducible representations. W…
Matching Lagrangian and Hamiltonian Simulations in (2+1)-dimensional U(1) Gauge Theory
C. F. GroÃ, 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…
