  Abstract:
We report on a theoretical study of the influence of electron-electron interactions on ARPES spectra in graphene that is based on the random-phase-approximation and on graphene's massless Dirac equation continuum model. We find that level repulsion between bare holes and a strong plasmaron resonance gives rise to a gap-like feature at small k. ARPES spectra are sensitive to the electron-electron interaction coupling strength αgr and might enable an experimental determination of this material parameter.
