Abstract:

We employ the constituent quark model and the generalized Pauli principle to compute the strange diquark interaction energies in quark-gluon plasma within the framework of an effective φ⁴ theory. The cases of strange diquarks (a pair of ss quarks) and hybrid diquarks (a pair of s and u or d quarks) are investigated in great detail. These results are used to derive equations of state for the strange diquark matter. The Tolman-Oppenheimer-Volkoff equations in conjunction with the derived equations of state are solved to obtain the masses and radii of strange diquark stars.
