Nucleon structure in terms of OPE with non-perturbative Wilson coefficients
W. Bietenholz, N. Cundy, M. Gockeler +7
Lattice calculations could boost our understanding of Deep Inelastic Scattering by evaluating moments of the Nucleon Structure Functions. To this end we study the product of electr…
The electric dipole moment of the nucleon from simulations at imaginary vacuum angle theta
R. Horsley, T. Izubuchi, Y. Nakamura +4
We compute the electric dipole moment of proton and neutron from lattice QCD simulations with N_f=2 flavors of dynamical quarks at imaginary vacuum angle theta. The calculation pro…
Perturbative determination of for plaquette and Symanzik gauge action and stout link clover fermions
R. Horsley, H. Perlt, P. E. L. Rakow +2
Using plaquette and Symanzik improved gauge action and stout link clover fermions we determine the improvement coefficient in one-loop lattice perturbation theory from the…
Nucleon distribution amplitudes from lattice QCD
Meinulf Göckeler, Roger Horsley, Thomas Kaltenbrunner +8
We calculate low moments of the leading-twist and next-to-leading twist nucleon distribution amplitudes on the lattice using two flavors of clover fermions. The results are present…
Dynamical QCD simulation with theta terms
Taku Izubuchi, Sinya Aoki, Koichi Hashimoto +3
The theta term that breaks the Strong CP symmetry is introduced in the two flavors of dynamical QCD simulation. theta is analytically continued to a pure imaginary number to make t…
