We present numerical calculations of the impact of charge carriers-carriers interactions on the
dynamical properties of quasiparticles such as renormalized velocity and quasiparticle inelastic scat-
tering lifetime in a gapped graphene sheet. Our formalism is based on the many-body G0W-
approximation for the self-energy. We present results for the many-body renormalized velocity
suppression and the renormalization constant over a broad range of energy gap values. We �nd that
the renormalized velocity is almost independence of the carrier densities at large density regime. We
also show that the quasiparticle inelastic scattering lifetime decreases by increasing the gap value.
Finally, we present results for the mean free path of charge carriers suppression over the energy gap
values.
