Quasiparticle dispersion in Bi2Sr2CaCu2O8 is investigated with improved
angular resolution as a function of temperature and doping. Unlike
the linear dispersion predicted by the band calculation, the data
show a sharp break in dispersion at 50±15 meV binding energy where
the velocity changes by a factor of 2 or more. This change provides
an energy scale in the quasiparticle self-energy. This break in dispersion
is evident at and away from the d-wave node line, but the magnitude
of the dispersion change decreases with temperature and with increasing
doping.
