Query: Theory of high energy features in angle-resolved photo-emission spectra
  of hole-doped cuprates   The recent angle-resolved photoemission measurements performed up to binding
energies of the order of 1eV reveals a very robust feature: the nodal
quasi-particle dispersion breaks up around 0.3-0.4eV and reappears around
0.6-0.8eV. The intensity map in the energy-momentum space shows a waterfall
like feature between these two energy scales. We argue and numerically
demonstrate that these experimental features follow naturally from the strong
correlation effects built in the familiar t-J model, and reflect the connection
between the fermi level and the lower Hubbard band. The results were obtained
by a mean field theory that effectively projects electrons by quantum
interference between two bands of fermions instead of binding slave particles.
