TL;DR
This paper investigates the mass spectra of fully heavy dibaryons using an extended chromomagnetic model, finding no stable states below baryon-baryon thresholds and providing decay width estimates to aid future experimental searches.
Contribution
It introduces an extended chromomagnetic model to analyze fully heavy dibaryons, including both colorelectric and chromomagnetic interactions, and offers predictions on their stability and decay properties.
Findings
No stable fully heavy dibaryon states below baryon-baryon thresholds.
Mass spectra calculated with the extended chromomagnetic model.
Estimated relative decay width ratios for two-body channels.
Abstract
We systematically study the mass spectra of the fully heavy dibaryons in an extended chromomagnetic model, which includes both the colorelectric and chromomagnetic interactions. We find no stable state below the corresponding baryon-baryon thresholds. Besides the masses, we also estimate the relative width ratios of the two-body decay channels. We hope our study will be of help for future experiments.
