Abstract
We present a simple albeit self-consistent approach to the spectral function of light quarks in infinite quark matter. Relations between correlation functions and collision rates are used to calculate the spectral function in an iterative procedure. The quark interactions are described by the SU(2) Nambu--Jona-Lasinio model. Calculations were performed in the chirally restored phase at zero temperature.
