van der Waals constants for the diquark and triquark, as well as different representations of the internal structure of the hexaquark.

We explore the chemical potential of a QCD-motivated van der Waals (VDW) phase change model for the six-quark color-singlet, strangeness S=-2 particle known as the hexaquark with quark content (uuddss). The hexaquark may have internal structure, indicated by short range correlations, that allow for non-color-singlet diquark and triquark configurati...

... composite particle states are constructed using the quark values from Table 1 with color factors to match the resulting state and find the chemical potential. These values represent the scalar S ground states which are nearly 220 MeV below their axial counterparts and are given in Table 2 [67,68]. These values can then be used with Equations (6) and (7) to express the chemical potentials as functions of temperature; plots for special cases are given in Figure 1 In our analysis, the chemical potential, which depends upon b2, needs to be realvalued, and this provides an additional constraint on Equation (6) giving a relationship between a, n, T, and the chemical potential These results can be applied to an environment where the Fermi energy is on the order of the chemical potential to explore shifts in the chemical potential, such as in a dense stellar core, which can be modeled using the TOV equations. ...
