根据LHC Higgs数据在SUSY SO(10)中的Yukawa统一

Yukawa unification in SUSY SO(10) in light of the LHC Higgs data

Marcin Badziak

摘要:

回顾了在超对称SO(10)模型中,上-下-τ Yukawa耦合统一的现状,特别强调了LHC Higgs数据所表明的希格斯玻色子质量在125 GeV附近的意义.此外,在125 GeV的Higgs背景下,重新分析了最近提出的SU(5)\subset SO(10)24维表象中非零F项产生的软标量质量和非普适Gaugino质量的负μ,D项分裂模型.上-下-τ汤川统一的条件加上希格斯粒子的质量约为125 GeV,对超对称粒子施加了较强的质量下限。尽管如此,一些MSSM粒子可能在LHC的范围内。在μ为正的模型中,这就是胶子。而在负μ的情况下,它们是赝标希格斯粒子、较轻的sbottom粒子(有时与LSP强烈简并,导致sbottom共湮灭)、右手夸克和胶子。

英文摘要:

The status of top-bottom-tau Yukawa coupling unification in supersymmetric SO(10) models is reviewed with a particular emphasis on the implications of the Higgs boson mass in the vicinity of 125 GeV, as suggested by the LHC Higgs data. In addition, the recently proposed model with negative μ, D-term splitting of the soft scalar masses and non-universal gaugino masses generated by a non-zero F-term in a 24-dimensional representation of SU(5) \subset SO(10) is re-analysed in the context of the 125 GeV Higgs. The condition of top-bottom-tau Yukawa unification together with the Higgs mass of about 125 GeV impose strong lower mass limits on SUSY particles. Nevertheless, some of the MSSM particles may be within the reach of the LHC. In the case of models with positive μthis is the gluino. While in the case of negative μthese are the pseudoscalar Higgs, the lighter sbottom (sometimes strongly degenerate with the LSP leading to sbottom coannihilations), the right-handed down squark and the gluino.
