Gluinonia: Energy Levels, Production and Decay

TL;DR

This paper provides detailed theoretical predictions for the energy levels, production mechanisms, and decay rates of gluinonia, which are bound states of gluinos, including higher-order QCD corrections and potential experimental signatures.

Contribution

It offers the first comprehensive calculation of gluinonia properties with next-to-next-to-leading order potentials and one-loop QCD corrections for production and decay processes.

Findings

Decay into gluon jets with a signal-to-background ratio of about 0.5%.

Potential detectability of light gluinos via bound states.

Quantitative predictions for energy levels and decay rates.

Abstract

Predictions for energy levels, production and decay rate of gluinonia, non-relativistic boundstates of gluinos, are presented. The potential between color-octet constituents is derived in next-to-next-to leading order and one-loop QCD corrections are derived for the production cross section and the decay rate into gluon jets. In addition we evaluate the decay rate into top quarks and into two photons. The signal-to-background ratio is estimated for the dominant decay mode and found to be around 0.5%. For relatively light gluinos the bound states thus might be detectable.
