扩展希格斯模型的景观意义

Landscape Implications of Extended Higgs Models

L. Clavelli

摘要:

从几个角度来看,强烈建议目前的宇宙是不稳定的,最终将衰减到一个完全超对称(susy)。原子和分子在这个未来宇宙中形成的可能性要求简并电子/选择子质量是非零的,因此电弱对称性破缺(EWSB)在相变中幸存下来。然而,最小超对称标准模型(MSSM)和它的几个扩展没有EWSB在susy极限。在已经讨论过的扩展希格斯模型中,有一个在这方面很突出。因此,在大型强子对撞机(LHC)上发现的希格斯扇区将对未来宇宙产生影响。我们还解决的问题,是否过渡到确切的SUSY阶段与EWSB是放热的。

英文摘要:

From several points of view it is strongly suggested that the current universe is unstable and will ultimately decay to one that is exactly supersymmetric (susy). The possibility that atoms and molecules form in this future universe requires that the degenerate electron/selectron mass is non-zero and hence that electroweak symmetry breaking (EWSB) survives the phase transition to exact susy. However, the minimal supersymmetric standard model (MSSM) and several of its extensions have no EWSB in the susy limit. Among the extended higgs models that have been discussed one stands out in this regard. The higgs sector that is revealed at the Large Hadron Collider (LHC) will therefore have implications for the future universe. We also address the question as to whether the transition to the exact susy phase with EWSB is exothermic.
