在自然的SUSY中触底

Hitting sbottom in natural SUSY

Hyun Min Lee, Veronica Sanz, Michael Trott

摘要:

我们比较直接停止和sbottom对生产搜索在大型强子对撞机的实验前景。这样的搜索停止是非常有趣的,因为他们直接探测的状态,是由超对称解的希格斯质量参数的层次问题的动机-导致一个“自然”的超对称谱。注意到,sbottom搜索是较少的实验挑战性和规模直接达到与B-标记算法的改进,我们讨论了小TeV规模的保管对称违反sbottom直接对生产搜索的相互作用,以获得强大的子TeV的限制停止在一个自然的超对称性的情况下的路径。我们认为,如果一个弱尺度自然超对称谱不存在LHC的范围内,那么希望这样的频谱参数空间的大区域应该sbottom了。相反,同样的论点清楚地表明,这样一个频谱的发现可能会以自下而上的方式进行。

英文摘要:

We compare the experimental prospects of direct stop and sbottom pair production searches at the LHC. Such searches for stops are of great interest as they directly probe for states that are motivated by the SUSY solution to the hierarchy problem of the Higgs mass parameter - leading to a "Natural" SUSY spectrum. Noting that sbottom searches are less experimentally challenging and scale up in reach directly with the improvement on b-tagging algorithms, we discuss the interplay of small TeV scale custodial symmetry violation with sbottom direct pair production searches as a path to obtaining strong sub-TeV constraints on stops in a natural SUSY scenario. We argue that if a weak scale natural SUSY spectrum does not exist within the reach of LHC, then hopes for such a spectrum for large regions of parameter space should sbottom out. Conversely, the same arguments make clear that a discovery of such a spectrum is likely to proceed in a sbottom up manner.
