The electric dipole moment of the nucleon from simulations at imaginary vacuum angle theta

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/167039We 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 proceeds via the CP odd form factor F_3. A novel feature of our calculation is that we use partially twisted boundary conditions to extract F_3 at zero momentum transfer. As a byproduct, we test the QCD vacuum at nonvanishing theta.22 pages, 10 figuresHigh Energy Physics - LatticeThe electric dipole moment of the nucleon from simulations at imaginary vacuum angle thetatext
