翻转双Higgs模型中的带电Higgs现象

Charged Higgs phenomenology in the flipped two Higgs doublet model

Heather E. Logan, Deanna MacLennan

摘要:

在“翻转”的双Higgs偶线模型中研究了带电希格斯玻色子的唯象,其中一个偶线给上型夸克和带电轻子以质量,另一个偶线给下型夸克以质量.我们给出了荷电希格斯粒子的分支比,并总结了间接约束。我们将现有的LEP搜索H+H-和Tevatron搜索t tbar(t -> H+ b)外推到翻转模型中,并提取对MH+和参数tan(beta)的约束。最后,我们通过回顾现有的LHC带电希格斯粒子搜索,并建议在这个模型中的LHC范围可以扩展到带电希格斯粒子质量低于tb阈值,考虑t tbar与t --> H+ b和H+ --> q qbar,因为已经在Tevatron搜索。

英文摘要:

We study the phenomenology of the charged Higgs boson in the "flipped" two Higgs doublet model, in which one doublet gives mass to up-type quarks and charged leptons and the other gives mass to down-type quarks. We present the charged Higgs branching ratios and summarize the indirect constraints. We extrapolate existing LEP searches for H+H- and Tevatron searches for t tbar with t --> H+ b into the flipped model and extract constraints on MH+ and the parameter tan(beta). We finish by reviewing existing LHC charged Higgs searches and suggest that the LHC reach in this model could be extended for charged Higgs masses below the tb threshold by considering t tbar with t --> H+ b and H+ --> q qbar, as has been used in Tevatron searches.
