Query: The neutron resonance: modeling photoemission and tunneling data in the
  superconducting state of Bi_2Sr_2CaCu_2O_{8+d}   Motivated by neutron scattering data, we develop a model of electrons
interacting with a magnetic resonance and use it to analyze angle resolved
photoemission (ARPES) and tunneling data in the superconducting state of
Bi_2Sr_2CaCu_2O_{8+d}. We not only can explain the peak-dip-hump structure
observed near the (pi,0) point, and its particle-hole asymmetry as seen in SIN
tunneling spectra, but also its evolution throughout the Brillouin zone,
including a velocity `kink' near the d-wave node.
