Abstract
Searches for the direct production of third generation supersymmetry at CMS are presented. The analyses use the full 8s=8 TeV dataset recorded by the CMS experiment, corresponding to approximately 20fb−1. This paper presents a search for top squark production in the final state with a single lepton. The statistical combination of the single lepton search with an inclusive hadronic search significantly extends the reach. A search utilizing single and double lepton final states is sensitive to the production of the heavier top squark mass eigenstate. Bottom squark production is probed with a fully hadronic search. No statistically significant excesses above the Standard Model background expectation are observed.
Highlights
The newly discovered Higgs boson [1][2] is difficult to be fully interpreted in the context of the standard model (SM)
Radiative corrections to the Higgs boson self-energy via SM particles require a high level of parameter fine-tuning, known as the hierarchy problem [3]
Due to the fact that the radiative corrections to the Higgs mass depend on the masses of the SM particles, a natural solution to the hierarchy problem requires light third generation squarks, with a mass up to the TeV scale [4]
Summary
The newly discovered Higgs boson [1][2] is difficult to be fully interpreted in the context of the standard model (SM). Radiative corrections to the Higgs boson self-energy via SM particles require a high level of parameter fine-tuning, known as the hierarchy problem [3]. Due to the fact that the radiative corrections to the Higgs mass depend on the masses of the SM particles, a natural solution to the hierarchy problem requires light third generation squarks, with a mass up to the TeV scale [4]. The CMS collaboration [5] has developed a very diverse 3rd generation SUSY search program that is sensitive to a large range of signal topologies. They range in both the type and parameters of produced particles in addition to their decay channels. All results are presented in the context of limits on produced SUSY particle masses
