First moment of the flavour octet nucleon parton distribution function using lattice QCD
C. Alexandrou, M. Constantinou, S. Dinter +5
We perform a lattice computation of the flavour octet contribution to the average quark momentum in a nucleon, $\la x\ra^{(8)}_{μ^2 = 4 \gev^2}$. In particular, we fully take the…
Sigma terms and strangeness content of the nucleon with twisted mass fermions
C. Alexandrou, M. Constantinou, S. Dinter +6
We investigate excited state contaminations in a direct computation of the nucleon -terms. This is an important source of systematic effects that needs to be controlled besides…
Nucleon scalar matrix elements with twisted mass fermions
S. Dinter, V. Drach, K. Jansen
We investigate scalar matrix elements of the nucleon using flavors of maximally twisted mass fermions at a fixed value of the lattice spacing of $a\approx 0.078{\rm fm}…
Nucleon form factors and moments of generalized parton distributions using twisted mass fermions
C. Alexandrou, M. Constantinou, S. Dinter +4
We present results on the axial and the electromagnetic form factors of the nucleon, as well as, on the first moments of the nucleon generalized parton distributions using maximall…
