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…
HLbL contribution to the muon g-2 using twisted-mass fermions at the physical point
N. Kalntis, G. Kanwar, M. Petschlies +2
We present updated results for the hadronic light-by-light (HLbL) contribution to the muon anomalous magnetic moment. The calculations are based on ETMC's Wilson-clover…
resonance form factors from in lattice QCD
Luka Leskovec, Stefan Meinel, Marcus Petschlies +3
The decay is an attractive process for determining the magnitude of the smallest CKM matrix element, , and can provide new insights into the origin…
Quark and gluon momentum fractions in the pion and in the kaon
Constantia Alexandrou, Simone Bacchio, Martha Constantinou +9
We present results on the momentum fraction carried by quarks and gluons in the pion and the kaon. We employ three gauge ensembles generated with Wilson twisted-mass cl…
Hadronic light-by-light contribution to the muon using twisted-mass fermions
Nikolaos Kalntis, Gurtej Kanwar, Marcus Petschlies +2
We report on our preliminary results from the lattice-QCD computation of the hadronic light-by-light (HLbL) contribution to the anomalous magnetic moment of the muon. We use twiste…
Investigation of contributions to nucleon matrix elements
Constantia Alexandrou, Giannis Koutsou, Yan Li +2
We investigate an improved method to extract nucleon matrix elements from lattice 3-point functions using a generalized eigenvalue problem (GEVP) with nucleon and pion-nucleon inte…
