希格斯玻色子质量和高光度LHC类矢量顶夸克超对称探测

Higgs boson mass and high-luminosity LHC probes of supersymmetry with vectorlike top quark

Zygmunt Lalak, Marek Lewicki, James D. Wells

摘要:

我们考虑一个扩展的MSSM与一个额外的矢量顶级合作伙伴。我们的目标是重新审视这种扩展在多大程度上可以通过辐射修正提高希格斯玻色子的质量,并帮助改善MSSM的层次问题,并指定在LHC的实验探测器将发现或排除这种可能性在高光度阶段。直接探测、精密电弱和精密希格斯分析都是为此目的委托进行的。为了获得$ 125 \, \textrm{GeV} \ $希格斯玻色子的质量,我们发现,在这种情况下,超伙伴质量可以减少超过三倍的MSSM相比,没有额外的矢量顶夸克,并在高亮度阶段的大型强子对撞机精确希格斯分析预计将成为最强大的实验探针的情况。

英文摘要:

We consider an extension of the MSSM with an added vectorlike top partner. Our aim is to revisit to what extent such an extension can raise the Higgs boson mass through radiative corrections and help ameliorate the MSSM hierarchy problem, and to specify what experimental probes at the LHC will find or exclude this possibility during the high-luminosity phase. Direct detection, precision electroweak and precision Higgs analyses are all commissioned to this end. To achieve the $ 125 \, \textrm{GeV} \ $ Higgs boson mass, we find that superpartner masses can be reduced by a factor of more than three in this scenario compared to the MSSM without the extra vectorlike top quark, and that during the high-luminosity phase of the LHC precision Higgs analysis is expected to become the most powerful experimental probe of the scenario.
