Phenomenological mass model for exotic hadrons and predictions for masses of non-strange dibaryons as hexaquarks

We investigate the mass spectra of exotic hadrons known as hexaquarks in the form of dibaryons. We use a phenomenological model based on an extended version of the Gürsey–Radicati mass formula for hadrons to include non-charmed baryons, charmed baryons, and non-strange dibaryons to be able to predic...
