Dynamical study of γ*N transition with N(e,e'p)π
Abstract
The Dubna-Mainz-Taipei (DMT) dynamical model for pion electromagnetic production, which describe well the existing data from threshold up to 1 GeV photon lab energy is presented and used to analyze recent data in the region . We find that within DMT model, the bare is almost spherical while the physical is oblate. The deformation is almost saturated by the pion cloud effects.
