非手征弱荷多重态的LHC方法

LHC Searches for Non-Chiral Weakly Charged Multiplets

Matthew R. Buckley, Lisa Randall, Brian Shuve

摘要:

由于大型强子对撞机探测的TeV尺度应该能揭示自然性、层次和暗物质问题,因此迄今为止的大多数搜索都集中在这些难题的可能解决方案所激发的新物理特征上。在本文中,我们考虑了一些新的国家,虽然没有很好的动机,从这个角度来看,明显的可能性,目前的搜索策略会错过。特别是,我们认为矢量表示的费米子在多重的$SU(2)_L$与最轻的中性状态。标准的搜索策略将无法找到这样的粒子,因为带电和中性状态之间预期的小的单圈能级分裂。

英文摘要:

Because the TeV-scale to be probed at the Large Hadron Collider should shed light on the naturalness, hierarchy, and dark matter problems, most searches to date have focused on new physics signatures motivated by possible solutions to these puzzles. In this paper, we consider some candidates for new states that although not well-motivated from this standpoint are obvious possibilities that current search strategies would miss. In particular we consider vector representations of fermions in multiplets of $SU(2)_L$ with a lightest neutral state. Standard search strategies would fail to find such particles because of the expected small one-loop-level splitting between charged and neutral states.
