Exploring sensitivity to NMSSM signatures with low missing transverse energy at the LHC

Exploring sensitivity to NMSSM signatures with low missing transverse energy at the LHC
Exploring sensitivity to NMSSM signatures with low missing transverse energy at the LHC

We examine scenarios in the Next-to-Minimal Supersymmetric Standard Model (NMSSM), where pair-produced squarks and gluinos decay via two cascades, each ending in a stable neutralino as Lightest Supersymmetric Particle (LSP) and a Standard Model (SM)-like Higgs boson, with mass spectra such that the missing transverse energy, ET miss, is very low. Performing two-dimensional parameter scans and focusing on the hadronic H→ bb¯ decay giving a bb¯bb¯+ETmiss final state we explore the sensitivity of a current LHC general-purpose jets + ET miss analysis to such scenarios.

Abstract

We examine scenarios in the Next-to-Minimal Supersymmetric Standard Model (NMSSM), where pair-produced squarks and gluinos decay via two cascades, each ending in a stable neutralino as Lightest Supersymmetric Particle (LSP) and a Standard Model (SM)-like Higgs boson, with mass spectra such that the missing transverse energy, ET miss, is very low. Performing two-dimensional parameter scans and focusing on the hadronic H→ bb¯ decay giving a bb¯bb¯+ETmiss final state we explore the sensitivity of a current LHC general-purpose jets + ET miss analysis to such scenarios.
