Abstract: The average density of states of two- and three-dimensional Weyl fermions is studied in the self-consistent Born approximation (SCBA) and its corrections. The latter have been organized in terms of a $1/N$ expansion. It turns out that an expansion in terms of the disorder strength is not applicable, as previously mentioned by other authors. Nevertheless, the $1/N$ expansion provides a justification of the SCBA as the large $N$ limit of Weyl fermions.
