Recently, angle-resolved photoemission spectroscopy (ARPES) has revealed
a dispersion anomaly at high binding energy near 0.3–0.5 eV in various
families of the high-temperature superconductors. For further studies
of this anomaly, we present a new two-dimensional fitting scheme
and apply it to high-statistics ARPES data of the strongly overdoped
Bi2Sr2CuO6 cuprate superconductor. The procedure allows us to extract
the self-energy in an extended energy and momentum range. It is found
that the spectral function of Bi2Sr2CuO6 can be parametrized using
a small set of tight-binding parameters and a weakly momentum-dependent
self-energy up to 0.7 eV in binding energy and over the entire first
Brillouin zone. Moreover, the analysis gives an estimate of the momentum
dependence of the matrix element, a quantity, which is often neglected
in ARPES analyses.
