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…
Investigation of pion-nucleon contributions to nucleon matrix elements
Constantia Alexandrou, Giannis Koutsou, Yan Li +2
We investigate contributions of excited states to nucleon matrix elements computed in lattice QCD by employing, in addition to the standard nucleon interpolating operator, pion-nuc…
Quark and gluon momentum fractions in the pion and in the kaon
Constantia Alexandrou, Simone Bacchio, Martha Constantinou +9
We present the full decomposition of the momentum fraction carried by quarks and gluons in the pion and the kaon. We employ three gauge ensembles generated with Wilson…
Lattice outlook on and
Luka Leskovec, Stefan Meinel, Marcus Petschlies +4
Lattice Quantum Chromodynamics (QCD) has significantly contributed to our understanding of the CKM matrix through precise determinations of hadronic matrix elements. With advanceme…
Investigation of two-particle contributions to nucleon matrix elements
Constantia Alexandrou, Giannis Koutsou, Yan Li +2
We investigate contributions of excited states to nucleon matrix elements by studying the two- and three-point functions using nucleon and pion-nucleon interpolating fields. This s…
