Query: On the Dipole Picture in the Nonforward Direction   We calculate, for nonzero momentum transfer, the dipole formula for the high
energy behaviour of elastic and quasielastic scattering of a virtual photon. We
obtain an expression of the nonforward photon impact factor and of the
nonforward photon wave function, and we give a physical interpretation.
