  We investigate in a microscopical transport model the evolution of conical
structures originating from the supersonic projectile moving through the matter
of ultrarelativistic particles. Using different scenarios for the interaction
between projectile and matter, and different transport properties of the
matter, we study the formation and structure of Mach cones. Furthermore, the
two-particle correlations for different viscosities are extracted from the
numerical calculations and we compare them to an analytical approximation. In
addition, by adjusting he cross section we investigate the influence of the
viscosity to the structure of Mach cones.
