摘要:
早先的一篇论文表明,可以写下无法定义超对称(SUSY)荷的新SUSY作用量。在这些新作用量中,SUSY是通过它们满足主方程(Master Equations)来定义的。新的SUSY作用量非常容易写下。只需取一个手征SUSY作用量,与规范和其他手征多重态耦合,如果需要,甚至可以与超引力耦合。然后,通过将标量场$S$的全部或部分替换为新的Zinn源$J$,并将相应的Zinn源$Γ$部分替换为新的反鬼场$η$,即可从中创建新作用量。由于原作用量满足主方程,这种替换保证了新作用量将满足新的主方程。如早先论文所示,新多重态的玻色子自由度少于费米子自由度。这是可能的,因为它们没有超荷。由此产生的新SSM不需要超夸克或超轻子。它不需要SUSY的自发破缺,因此不会出现宇宙学常数问题(至少在树图阶)。它很好地模仿了通常的非超对称标准模型,并且大味改变中性流的缺失是自然的。不需要隐藏部分、信使部分或SUSY的显式“软”破缺。自发规范对称性破缺意味着存在两个新的极重希格斯玻色子,质量为13.4 TeV,略小于LHC的14 TeV能量。还有一组奇特的重子微子(Gauginos)和希格斯微子,它们与希格斯和规范玻色子具有完全相同的质量。它们不与夸克和轻子耦合,除非通过希格斯和规范玻色子。
英文摘要:
An earlier paper showed that it is possible to write down new SUSY Actions in which it is not possible to define a Supersymmetry Charge. SUSY is defined in these new Actions by the fact that they satisfy Master Equations. The new SUSY Actions are very easy to write down. One simply takes a Chiral SUSY Action, coupled to Gauge and other Chiral Multiplets, and even SuperGravity, if desired. Then one creates a new Action from this by exchanging all or part of the Scalar Field $S$ for a new Zinn Source $J$, and the corresponding part of the Zinn Source $Γ$ for a new Antighost Field $η$. Since the original Action satisfies a Master Equation, this exchange guarantees that the new Action will satisfy the new Master Equation. As was shown in the earlier paper, the new multiplets have fewer bosonic degrees of freedom than fermionic degrees of freedom. This is possible because they do not have a Supercharge. The resulting new SSM has no need for Squarks or Sleptons. It does not need spontaneous breaking of SUSY, so that the cosmological constant problem does not arise (at least at tree level). It mimics the usual non-supersymmetric Standard Model very well, and the absence of large flavour changing neutral currents is natural. There is no need for a hidden sector, or a messenger sector, or explicit `soft' breaking of SUSY. Spontaneous Gauge Symmetry Breaking implies the existence of two new very heavy Higgs Bosons with mass 13.4 TeV, slightly smaller than the energy of the LHC at 14 TeV. There is also a curious set of Gauginos and Higgsinos which have exactly the same masses as the Higgs and Gauge Bosons. These do not couple to the Quarks and Leptons, except through the Higgs and Gauge Bosons.
