We study how multiple charge excitations appear in the resonant inelasticx-ray scattering (RIXS) spectra of metals. The single excitations in theproblem are the plasmons and electron-hole pairs, and multi-excitationprocesses are usually neglected. However, at small momentum transfer themulti-excitation contributions may dominate the signal and one needs tounderstand how to interpret the data. In particular, we demonstrate how to"decode" the total multi-excitation intensity and extract the plasmondispersion. While our calculations are based on the random phase approximation,which does not allow to obtain quantitatively precise results in the entireregion of parameters, we expect them to capture semi-qualitatively all featuresexpected for charged Fermi-liquid states, including universal and singularproperties of the RIXS spectra.
