超对称模型中的标量顶会在量子水平上影响标准模型（如希格斯粒子）的势。根据等效定理，可以用纵向规范玻色子来追踪势与标准模型的偏差。在这项工作中，研究了在tev尺度标量顶场景下的高能纵向白色子散射，发现微分截面上与标准模型预测的偏差，这取决于观测到的希格斯质量是仅由标量顶解释还是由更高尺度上的附加贡献解释。
Scalar tops in the supersymmetric model affect the potential of the standard model-like Higgs at the quantum level. In light of the equivalence theorem, the deviation of the potential from the standard model can be traced by longitudinal gauge bosons. In this work, high-energy longitudinalboson scattering is studied in a TeV-scale scalar top scenario.deviation from the standard model prediction in the differential cross section is found, depending on whether the observed Higgs mass is explained only by scalar tops or by additional contributions at a higher scale.
