Abstract

We amend ab initio strongly correlated band structures by taking into account the band-tailing phenomenon in doped charge-transfer Mott-Hubbard insulators. We show that the photoemission from band tails accounts for sharp ``quasiparticle'' peaks, rapid loss of their intensities in some directions of the Brillouin zone (``Fermi arcs''), and high-energy ``waterfall'' anomalies as a consequence of matrix-element effects of disorder-localized states in the charge-transfer gap of doped cuprates.
