摘要:

万亿级将随着大型强子对撞机的启动而被探索。电弱对称性破缺的根源和希格斯机制是否在自然界中实现是我们期待得到解答的最基本的问题之一。在这种情况下,我们提出的问题,如果现有的实验数据仍然允许一个轻的非最小希格斯部门。我们首先解决这个问题的背景下,两个希格斯偶极子模型,然后我们集中在两个超对称模型,约束MSSM和MSSM与非普遍的希格斯质量。在这两种超对称情形中,只要tan β很大,轻赝标和轻荷电希格斯玻色子玻色子仍然是可行的。在这个制度中,我们强调的重要性,提供的约束衰变B到τ nu介导的带电希格斯粒子在树的水平。此外,我们评论强子对撞机和间接搜索在这种情况下的一般预测。

英文摘要:

The terascale will be explored with the start of the LHC. One of the most fundamental questions which we expect to be answered is the root of electroweak symmetry breaking and whether the Higgs mechanism is realized in nature or not. In this context we pose the question if existing experimental data still allow for a light non-minimal Higgs sector. We tackle this question first in the context of the two Higgs doublet model and then we concentrate in two supersymmetric models, the constrained MSSM and the MSSM with non-universal Higgs masses. In both supersymmetric scearios, light pseudoscalar and light charged-Higgs bosons are still viable provided tan beta is large. In this regime, we emphasize the importance of the constraints provided by the decay B to tau nu mediated by the charged-Higgs at tree-level. In addition we comment on generic predictions for hadronic colliders and indirect searches in such scenarios.
