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…
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…
