Abstract
The self-energy of an electron liquid is studied by including the infinite series of particle-hole and particle-particle ladder interactions beyond the RPA. The effects of these two local-field corrections on the quasiparticle dispersion, the chemical potential mu , the quasiparticle renormalisation factor zF and the effective-mass ratio m*/m have been numerically examined in the metallic density region.
