TL;DR
This paper explores the potential detection of stoponium, a supersymmetric bound state, in ongoing LHC Higgs searches, highlighting promising decay channels and current experimental constraints.
Contribution
It analyzes the detectability of stoponium in Higgs search channels and identifies promising mass ranges and decay modes for future searches.
Findings
Stoponium detection ratios in WW and ZZ channels can exceed unity.
Gamma gamma channel is also promising for detection.
Current experiments are probing stoponium masses below 150 GeV.
Abstract
Stoponium, a bound state of top squark and its antiparticle in a supersymmetric model, may be found in the ongoing Higgs searches at the LHC. Its WW and ZZ detection ratios relative to the Standard Model Higgs boson can be more than unity from WW* threshold to the two Higgs threshold. The gamma gamma channel is equally promising. Some regions of the stoponium mass below 150 GeV are already being probed by the ATLAS and CMS experiments.
