摘要:

在大型强子对撞机上,重子数违反相互作用可以修改超对称模型的特征。在这篇文章中,我们调查的最小超对称标准模型的局部重子和轻子数自发破缺在TeV尺度的一个简单的扩展中的希格斯质量和希格斯衰变的预测。该理论预言了在低尺度下的重子数破坏,它可以改变当前LHC超对称谱的边界。使用ATLAS和CMS边界上的希格斯粒子的质量,我们显示的sfermion质量的约束,并显示随后的预测辐射希格斯衰变。我们发现,由于新的轻轻子的存在,希格斯粒子衰变为两个光子的过程被抑制了。在这个理论中,停止可以很轻,与所有的实验界限一致,我们在大型强子对撞机的可能信号进行了简要的讨论。

英文摘要:

Baryon number violating interactions could modify the signatures of supersymmetric models at the Large Hadron Collider. In this article we investigate the predictions for the Higgs mass and the Higgs decays in a simple extension of the minimal supersymmetric standard model where the local baryon and lepton numbers are spontaneously broken at the TeV scale. This theory predicts baryon number violation at the low scale which can change the current LHC bounds on the supersymmetric spectrum. Using the ATLAS and CMS bounds on the Higgs mass we show the constraints on the sfermion masses, and show the subsequent predictions for the radiative Higgs decays. We found that the Higgs decay into two photons is suppressed due to the existence of new light leptons. In this theory the stops can be very light in agreement with all experimental bounds and we make a brief discussion of the possible signals at the LHC.
