heal.abstract |
The magnetic dipole, the electric quadrupole and the Coulomb quadrupoleamplitudes for the transition $\gamma N\to \Delta$ are evaluated both inquenched lattice QCD at $\beta=6.0$ and using two dynamical Wilson fermionssimulated at $\beta=5.6$. The dipole transition form factor is accuratelydetermined at several values of momentum transfer. On the lattices studied inthis work, the electric quadrupole amplitude |
