In this talk, I will discuss the description of plasmon-loss peaks in photoemission, and
their use to gain information on the sample. Among the two existing approaches in the
literature, I will favour Hedin's quasiboson formalism which blends very well within
multiple scattering theory. An extensive description of this model and how to
incorporate it into the formulation of the cross-section of photoemission will be
presented. Some preliminary results on the modelling will be shown and I will discuss
future developments to further improve the description.
