What is a mass independent renormalization scheme

  1. Jan 23, 2010 #1
    What is it meant by "mass-independent renormalization scheme"?

    Does it mean that the counter-terms that cancel the infinities do not have dimensions of mass? In this case, any regularization scheme not involving the cutoff method, such as dimensional regularization?

    Or does it mean that none of the counter-terms contain the mass 'm' of the particle?
    So that even in dimensional regularization scheme, when canceling the pole, you could also decide to also cancel a term like log(m/[tex]\mu[/tex]), which would make this mass-dependent?

    Is MS (or MS-bar) a mass-independent renormalization scheme?
