Abstract
The linewidths of the and bands originating from the electron-phonon coupling in graphene are analyzed based on model calculations and experimental angle-resolved photoemission spectroscopy (ARPES) data. We find evidence for crucial contributions to the lifetime broadening from interband scattering and , respectively, driven by the out-of-plane ZA acoustic phonons. The essential features of the calculated band linewidths are in agreement with recent published ARPES data [Mazzola et al., Phys. Rev. B 95, 075430 (2017)] and of the band linewidth with ARPES data presented here.
