Does the W mass run with energy as little as the electron mass?

  1. Jul 6, 2009 #1
    If I look up how the mass of the electron runs with energy between low energy and the Planck energy due to renormalization, the difference is only a few percent. I never found such a calculation of the W or the Z bosons. Is the effect equally small? Or is there a difference?

    Thank you very much for any help or any reference!

    Yes of course, I think one has made it up to at least 3loop order (Boughezal, Nucl Phys B 2005)
