In QFTtextbooks, the process of dynamical massgeneration is often used. For example one gets an effective quarkmass as a solution of the Schwinger Dysonequation. This mass is dependent on the quarks momentum. The effective quarkmass as a function of the momentum gives an image of the interaction between a quark and its surrounding virtual particles. For lowenergy quarks, the strong force coupling constant is very large because of asymptotic freedom. So in this condition, many virtual particles become real because of the strong interaction and thus quarkmass is generated. Is this conclusion right or am I making e few mistakes here? Can anyone give me a clear definition of the effective quarkmass, what does is really mean? How is mass generated dynamically Thanks a lot Nikolaas Van der Heyden Nikolaas.vanderheyden@ugent.be
