| 摘 要： | 应用对双Higgs二重态模型(THDM)进行幺正约束的方法对色八重态电弱二重态模型施加幺正约束,给出该模型中的Higgs质量的上下限,同时也考虑了来自STU变量和双光子的约束,其中后者的约束更严格.讨论了这些约束对CDF合作组观测到的W+jj′有3.2σ超出的影响和解释,对人们寻找Higgs粒子有一定的帮助作用.

| Abstract: | We studied unitarity constraints on color-octet-electroweak-doublet model.The method has been used on Two Higgs Doublets Model(THDM).Then we got bounds of Higgs mass.At the same time we concerned constraints from diphoton and STU variables and the later is more strict.After that,we focus on ’W+jj’ 3.2σ excess observed by the CDF collaboration,the constraints have the some influence on the excess which will do some favor on Higgs hunting. |
