Dirac plasmons in a doped graphene sheet have recently been shown to enableconfinement of light to ultrasmall volumes. In this work we calculate theintrinsic lifetime of a Dirac plasmon in a doped graphene sheet by analyzingthe role of electron-electron interactions beyond the random phaseapproximation. The damping mechanism at work is intrinsic since it operatesalso in disorder-free samples and in the absence of lattice vibrations. Wedemonstrate that graphene's sublattice-pseudospin degree of freedom suppressesintrinsic plasmon losses with respect to those that occur in ordinarytwo-dimensional electron liquids. We relate our findings to a microscopiccalculation of the homogeneous dynamical conductivity at energies below thesingle-particle absorption threshold.
