Standard model coupling strengths

  1. Jan 4, 2009 #1
    Hi guys,

    Where can i find the most up to date (accurate) values of the standard model coupling strengths at the mass of the Z boson? Thanks

    The particle data group:

    I think that what you are looking for is in the summary tables.

    (for the fine structure constant, see http://pdg.lbl.gov/2008/reviews/rpp2008-rev-phys-constants.pdf )

    EDIT: oops, I misread your question: I thought you asked for the standard coupling constant and the mass of the Z boson.

    What you ask for can be calculated from them, but you will depend on the exact renormalisation scheme you use (whatever you call 'the fine structure constant at Z mass' depends on your renormalisation scheme).
