We calculate the quasiparticle properties of chiral Dirac electrons in graphene
within the Landau Fermi Liquid scheme in the based on random phase approximation in the presence of disorder. We take randomly distributed charged
impurities at a fixed distance from the graphene sheet and surface
fluctuations (ripples) as the main scattering mechanisms. Mode-coupling
approach to scattering rate and self-energy in random-phase 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 $5-10$ percentage at available experimental charge carrier density region.
