Scalar tops in the supersymmetric model affect the potential of the standardmodel-like Higgs at the quatum level. In light of the equivalence theorem, thedeviation of the potential from the standard model can be traced bylongitudinal gauge bosons. In this work, high energy longitudinal W bosonscattering is studied in a TeV-scale scalar top scenario. O(1-10%) deviationfrom the standard model prediction in the differential cross section is founddepending on whether the observed Higgs mass is explained only by scalar topsor by additional contributions at a higher scale.
