Abstract
Motivated by neutron scattering data, we develop a model of electrons inter acting with a magnetic resonance and use it to analyze angle resolved photo emission and tunneling data in the superconducting state of Bi2Sr2CaCu2O8+d elta We not only can explain the peak-dip-hump structure observed near the (pi, 0) point, and its particle-hole asymmetry as seen in superconductor-in sulator-normal tunneling spectra, but. also its evolution throughout the Br illouin zone, including a velocity "kink" near the d-wave node.
