Diquark coupling in the NJL model is fixed near 1.5 times the scalar coupling and vector coupling below 1.1 times, yielding crossover equations of state that raise maximum neutron star masses and produce distinct radial oscillation frequencies potentially detectable as quark-matter signatures.

Crossover Equation of State Constrained by Astronomical Observations and pQCD
Diquark coupling in the NJL model is fixed near 1.5 times the scalar coupling and vector coupling below 1.1 times, yielding crossover equations of state that raise maximum neutron star masses and produce distinct radial oscillation frequencies potentially detectable as quark-matter signatures.
