Please, what is dynamical mass-generation ?

  1. please, what is dynamical mass-generation ???

    --------------------------------------------------------------------------------

    In QFT-textbooks, the process of dynamical mass-generation 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
    low-energy 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
