摘要：

扩展的标准模型希格斯扇区涉及弱三重态标量不仅是基准候选人，以协调观察到的异常最近发现的希格斯粒子，但也表现出一个巨大的参数空间，其中最轻的希格斯的现象是非常相似的标准模型之一。这个模型类的一个通用的预测是外来的双电荷标量粒子的外观。在本文中，我们适应现有的双轻子+丢失的能量+喷流测量的背景下，超对称性搜索占主导地位的衰变模式$H^{\pm\pm}\to W^\pm W^\pm$，并发现大型强子对撞机已经开始探测模型的参数空间。一个简单的修改对签名典型的弱玻色子融合搜索，使我们能够制定更严格的约束与7 TeV的LHC数据集。在14 TeV质心能量下对该通道进行的相应分析将在整个参数空间上约束模型，并促进潜在的$H^{\pm\pm}\to W^\pm W^\pm$发现。

英文摘要：

Extensions of the Standard Model Higgs sector involving weak isotriplet scalars are not only benchmark candidates to reconcile observed anomalies of the recently discovered Higgs-like particle, but also exhibit a vast parameter space, for which the lightest Higgs' phenomenology turns out to be very similar to the Standard Model one. A generic prediction of this model class is the appearance of exotic doubly charged scalar particles. In this paper we adapt existing dilepton+missing energy+jets measurements in the context of SUSY searches to the dominant decay mode $H^{\pm\pm}\to W^\pm W^\pm$ and find that the LHC already starts probing the model's parameter space. A simple modification towards signatures typical of weak boson fusion searches allows us to formulate even tighter constraints with the 7 TeV LHC data set. A corresponding analysis of this channel performed at 14 TeV center of mass energy will constrain the model over the entire parameter space and facilitate potential $H^{\pm\pm}\to W^\pm W^\pm$ discoveries.
