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…
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…
