Query: Manifestation of marginal Fermi liquid and phonon excitations in
  photoemision experiments of cuprate superconductors   Recent ARPES experiments in cuprates superconductors show a kink in the
electron dispersion near the Fermi energy. This kink coexists with a linear
frequency dependence of the imaginary part of the electron self-energy. In this
paper we show that both features could be accounted for if an electron-phonon
interaction is included in a model where the electrons are described by a
marginal Fermi liquid theory. Phonons provide the energy scale seen in the
experiments but the quasiparticle weight at the Fermi level is zero. At high
binding energy, in agreement with the experiment, the electron dispersion does
not go to the one-electron band.
  We analyze the compatibility between the electron scattering rate extracted
from ARPES experiment and the one extracted from transport properties. We
conclude that the electron-phonon interaction relevant for transport properties
is strongly screened respect to the one extracted from ARPES. This is in
agreement with recent studies in the context of 1/N expansion on t-J model.
