Query: On the Equation of State for Diquark Systems and their importance in
  Astrophysics and Cosmology   With a view to studying diquark formation in QCD phase transition and its
consequences in high energy density physics, the energy per quark for the
extended scalar diquarks (ESD) as a function of density is calculated, within
the framework of an effective phi four theory, for several values of the
effective interaction parameter (lamda). Various equations of state for the ESD
systems corresponding to the different values of lamda are obtained. The
importance of the equations of state for such matter under extreme conditions
of density and/or temperature is discussed and the role of the astrophysical
diquarks in astrophysics and cosmological diquarks in cosmological conditions
is also highlighted.
