First moment of the flavour octet nucleon parton distribution function using lattice QCD
(2015)Abstract: We perform a lattice computation of the flavour octet contribution to the average quark momentum in the nucleon, (Formula presented.). In particular, we fully take the disconnected contributions into account in ...

O(a 2) corrections to the one-loop propagator and bilinears of clover fermions with Symanzik improved gluons
(2009)We calculate corrections to the fermion propagator and to the Green's functions of all fermion bilinear operators of the form , to one-loop in perturbation theory. We employ the Wilson/clover action for fermions and the ...
