  Using Angle-Resolved Photoemission (ARPES), we present the first observation
of sharp quasiparticle-like peaks in a CMR manganite. We focus on the ($\pi$,0)
regions of k-space and study their electronic scattering rates and dispersion
kinks, uncovering the critical energy scales, momentum scales, and strengths of
the interactions that renormalize the electrons. To identify these bosons we
measured phonon dispersions in the energy range of the kink by inelastic
neutron scattering (INS), finding a good match in both energy and momentum to
the oxygen bond-stretching phonons.
