Query: Relation between the one-particle spectral function and dynamic spin
  susceptibility in superconducting Bi$_2$Sr$_2$CaCu$_2$O$_{8-\delta}$   Angle resolved photoemission spectroscopy (ARPES) provides a detailed view of
the renormalized band structure and, consequently, is a key to the self-energy
and the single-particle Green's function. Here we summarize the ARPES data
accumulated over the whole Brillouin zone for the optimally doped
Bi$_2$Sr$_2$CaCu$_2$O$_{8-\delta}$ into a parametric model of the Green's
function, which we use for calculating the itinerant component of the dynamic
spin susceptibility in absolute units with many-body effects taken into
account. By comparison with inelastic neutron scattering (INS) data we show
that the itinerant component of the spin response can account for the integral
intensity of the experimental INS spectrum. Taking into account the bi-layer
splitting, we explain the magnetic resonances in the acoustic (odd) and optic
(even) INS channels.
