Description

We examine scenarios in the Next to Minimal Supersymmetric Standard Model where pair-produced squarks and gluinos decay via two cascades, each ending in a stable neutralino LSP and a standard model Higgs with the mass gaps in the decay such that the Missing Transverse Energy is very small. Performing two-dimensional parameter scans and focusing on the hadronic h→$b\bar{b}$ decay giving a $b\bar{b}b\bar{b}$ + $E_{T}^{\text{miss}}$ final state we then explore the sensitivity of a current CMS $\alpha_{T}$-based general-purpose jets+$E_{T}^{\text{miss}}$ analysis to such scenarios with a view to developing novel search approaches in the near future.
