N to Delta electromagnetic transition form factors from Lattice QCD

Mostrar otras versiones (2)

The magnetic dipole, the electric quadrupole and the Coulomb quadrupole amplitudes for the transition $\gamma N\to \Delta$ are evaluated in lattice QCD. Unquenching effects are studied using two dynamical Wilson fermions. The dipole transition form factor is accurately determined at several values o...
