Importance of fermion loops $W^{+}{W}^{-}$ in elastic scattering

Abstract

We test the assumption that fermion-loop corrections to high energy $W^{+}{W}^{-}$ scattering are negligible when compared to the boson-loop ones. Indeed, we find that, if the couplings of the interactions deviate from their Standard Model values, fermion-loop corrections can in fact become as important or even greater than boson-loop corrections for some particular regions of the parameter space, and both types of loops should be taken into account. Some preliminary results are shown.
