W. Beenakker et Gj. Vanoldenborgh, THE EFFECT OF THE HIGGS-BOSON ON THE THRESHOLD CROSS-SECTION IN W-PAIR PRODUCTION, Physics letters. Section B, 381(1-3), 1996, pp. 248-254
We investigate the uncertainty induced by the Higgs-boson mass on the
determination of m(w) from the LEP-2 run near the threshold for W-pair
production. For a light Higgs boson the Yukawa interaction between th
e two slowly-moving W bosons gives rise to a correction of close to 1%
to the total cross-section. This corresponds to a 15 MeV shift in the
deduced W mass for a Higgs-boson mass of 60 GeV. We present a simple
approximation for this correction and discuss its validity.
