Phenomenological supersymmetry

A review on the Minimal Supersymmetric Standard Model (MSSM) is given, putting a special emphasis on the Higgs sector. The electroweak symmetry breaking in the context of the MSSM is analyzed. It is found that there are five Higgs bosons in the model, and their tree-level masses are determined. However these masses receive quantum corrections, which can be large if the particles involved in the loop diagrams have large masses. In this thesis, the one-loop correction, due to the top quark and stop squark loops, to the Higgs effective potential is obtained. It is found that such a one-loop correction changes the upper bound on the mass of the lightest Higgs boson substantially with the known value of top quark mass and a sufficiently high supersymmetry breaking scale.本文对最小超对称标准模型（Minimal Supersymmetric Standard Model，MSSM）展开综述，重点聚焦于其希格斯扇区。文中分析了该模型框架下的电弱对称性破缺机制，研究发现模型中共存在5种希格斯玻色子，并确定了它们的树图级质量。然而这些质量会受到量子修正；若圈图所涉及的粒子具有较大质量，则修正幅度可十分显著。本文得到了顶夸克与顶标量夸克（stop squark）圈图对希格斯有效势带来的单圈修正。结合当前已知的顶夸克质量取值与足够高的超对称破缺能标，该单圈修正会显著改变最轻希格斯玻色子质量的上限。
