薄型SUSY

Slim SUSY

Ernesto Arganda, J. Lorenzo Diaz-Cruz, Alejandro Szynkman

摘要:

最近在LHC发现的新的类SM希格斯玻色子,质量$m_h \simeq$ 125 GeV,以及LHC对超伴子质量的直接限制,它们进入TeV范围,表明SM(MSSM)的最小幸存超对称扩展,应该以重超对称破坏标度为特征。已经提出了MSSM的几个变体来解释这一结果,这些变体根据可接受的微调程度而变化。我们在这里提出了一个替代方案,Slim SUSY,它包含多TeV质量的sfermions和EW尺度附近的gauginos/higgsinos,但它也包括EW尺度附近的重MSSM希格斯玻色子($H^0$,$A^0$,$H^\pm$)。我们首先讨论的制定和限制的超薄超对称性的情况下,然后确定独特的重希格斯粒子的信号,可以在大型强子对撞机搜索,在场景中的最小数量的超伙伴与质量附近的EW规模。

英文摘要:

The new SM-like Higgs boson discovered recently at the LHC, with mass $m_h \simeq$ 125 GeV, as well as the direct LHC bounds on the mass of superpartners, which are entering into the TeV range, suggest that the minimal surviving supersymmetric extension of the SM (MSSM), should be characterized by a heavy SUSY-breaking scale. Several variants of the MSSM have been proposed to account for this result, which vary according to the accepted degree of fine-tuning. We propose an alternative scenario here, Slim SUSY, which contains sfermions with multi-TeV masses and gauginos/higgsinos near the EW scale, but it includes the heavy MSSM Higgs bosons ($H^0$, $A^0$, $H^\pm$) near the EW scale too. We discuss first the formulation and constraints of the Slim SUSY scenario, and then identify distinctive heavy Higgs signals that could be searched at the LHC, within scenarios with the minimal number of superpartners with masses near the EW scale.
