Updated Stealth SUSY scan involving two photons and multiple jets

Abstract

A Stealth SUSY scan was performed for squark mass (m_q̃) ranging from 1000 − 2000 GeV and bino mass (m_χ̃10) ranging from 200 − 450 GeV. At some points below the 1300 GeV squark mass, the atlas_1807_07447 analysis is the most sensitive search to the Stealth SUSY model. At higher squark masses, the atlas_1802_03158 analysis is the most sensitive; consistent to the result of a previous study. A benchmark point excluded by the atlas_1807_07447 analysis, but allowed by the atlas_1802_03158 analysis, was considered (m_q̃ = 1100 GeV/m_χ̃10 = 210 GeV). It was shown that the most sensitive signal region for this benchmark point involves two photons and multiple jets unlike the usual signal region involving missing transverse energy ( ̷E_T) for SUSY searches.
