Description
G2-QCD, i.e. QCD with the gauge group SU(3) replaced by the exceptional
group G(2), shares many features with SU(3). But it is accessible at
finite density on the lattice, as it has no sign problem, and at the
same time has a neutron.
Therefore, this theory can sustain in princple neutron star. Using the
equation of state for this theory from lattice simulations, we solve the
Oppenheimer-Volkoff equation and obtain the mass-radius-relation of such
neutron stars.
This study shows how different phases, visible in the equation of state,
influence the mass-radius relation, and therefore gives guidance for the
case of full QCD and true neutron stars.
