R宇称破缺超对称性中的锂离子希格斯玻色子质量

Lightest Higgs boson masses in the R-parity violating supersymmetry

Marek Góźdź

摘要:

关于希格斯玻色子搜索的第一个结果出现在今年夏天的LHC和Tevatron小组,最近已经得到了ATLAS和CMS实验的支持,这些实验在CERN的LHC上获得了数据。尽管这种粒子被探测到的兴奋还为时过早,但新的数据将最轻的希格斯玻色子$m_{h^0}$的质量限制在非常窄的120-140 GeV区域,可能的峰值约为125 GeV。在这篇文章中,我们简要介绍了一个最小超引力模型中的希格斯扇区,它具有破缺的R宇称。强加的约束$m_{h^0}$,我们表明,有一个相对较大的一组自由参数的模型,该约束得到满足。我们也indeterify点,导致最轻的希格斯玻色子质量约为125 GeV。此外,依赖的R-宇称混合的大小的模型进行了讨论。

英文摘要:

The first results on the searches of the Higgs boson appeared this Summer from the LHC and Tevatron groups, and has been recently backed up by the ATLAS and CMS experiments taking data at CERN's LHC. Even though the excitement that this particle has been detected is still premature, the new data constrain the mass of the lightest Higgs boson $m_{h^0}$ to a very narrow 120-140 GeV region with a possible peak at approximately 125 GeV. In this communication we shortly present the Higgs sector in a minimal supergravity model with broken R-parity. Imposing the constraint on $m_{h^0}$ we show that there is a relatively large set of free parameters of the model, for which that constraint is fulfilled. We indetify also points which result in the lightest Higgs boson mass being approximately 125 GeV. Also the dependence on the magnitude of the R-parity admixture to the model is discussed.
