Dissipative solitons (DSs) are self-organized structures in nonlinear dissipative systems with particle-like properties. They are known to exist in many different circumstances. DSs can be investigated in an exemplary manner in planar gas-discharge systems. On this poster, we give an overview of experimental observations. Among other things we observed propagation, scattering, formation of molecules, generation and annihilation. In case that the number of DSs is preserved, properties of DSs can be analyzed using stochastic data analysis. The basic mechanisms of the formation and the dynamics of DSs can be understood in terms of reaction-diffusion models that can be connected to microscopic models by adiabatically eliminating the fast time-scales in the system.
