Abstract
We calculate the quasiparticle properties of chiral two-dimensional Dirac electrons in graphene within the Landau Fermi Liquid scheme based on GW approximation in the presence of disorder. Disorder effects due to charged impurity scattering play a crucial role in density dependence of quasiparticle quantities. Mode-coupling approach to scattering rate and self-energy in GW approximation for quasiparticle renormalized Fermi velocity and spin-antisymmetric Landau Fermi parameter incorporating the many-body interactions and the disorder effects show reduction of these quantities by 5%-15% at available experimental charge carrier density region.
