Spectroscopy of \(\rm{q}^3\bar{\rm{q}}^3\)-States in Quark Model and Baryon-Antibaryon Enhancements

We study the mass spectrum of the \(\rm{q}^3\bar{\rm{q}}^3\) mesons both from the quark model with triquark correlations and from common quark model with colormagnetic interactions and with relative S-waves between quarks. Two cluster configurations \((\rm{q}^3)-(\bar{\rm{q}}^3)\) and \((\rm{q}^2\ba...

Description
Summary:We study the mass spectrum of the \(\rm{q}^3\bar{\rm{q}}^3\) mesons both from the quark model with triquark correlations and from common quark model with colormagnetic interactions and with relative S-waves between quarks. Two cluster configurations \((\rm{q}^3)-(\bar{\rm{q}}^3)\) and \((\rm{q}^2\bar{\rm{q}})-(\rm{q}\bar{\rm{q}}^2)\) are considered. In the spectrum we find rather stable states which have the same quantum number with particle resonances which are corresponding to the \(p\bar{p}\) enhancement, \(p\bar{\Lambda}\) enhancement and \(\Lambda\bar{\Lambda}\) enhancement with spin-\(\mathbf{0}\) or \(\mathbf{1}\). This imply these enhancements are NOT experimental artifacts. The color-spin-flavor structures of \(p\bar{p}\), \(p\bar{\Lambda}\), and \(\Lambda\bar{\Lambda}\) enhancements are revealed. The existence of spin-\(\mathbf{1}\) \(\Lambda\bar{\Lambda}, p\bar{\Lambda}, p\bar{p}\) enhancements is predicted.
