在这封信中，我们研究了双电荷希格斯玻色子质量的最新束缚，假设它们主要衰变为双玻色子。通过比较ATLAS合作组利用LHC 8 TeV运行的最新20.3 fb$^{-1}$数据对同号双轻子事件的包容性搜索和基于Higgs三重态模型的理论预测以及次高阶QCD修正，得到了新的束缚.我们发现$H^{\pm\pm}$上的质量下限约为84 GeV。
In this Letter, we study the latest bound on the mass of doubly charged Higgs bosons, $H^{\pm\pm}$, assuming that they dominantly decay into a diboson. The new bound is obtained by comparing the inclusive searches for events with a same-sign dilepton by the ATLAS Collaboration using the latest 20.3 fb$^{-1}$ data at the LHC 8 TeV run with theoretical prediction based on the Higgs triplet model with next-to-leading order QCD corrections. We find that the lower mass bound on $H^{\pm\pm}$ is about 84 GeV.
