Description
We discuss a model of quark-hadron duality to explain soft-to-stiff evolution of stiffness in neutron star equations of state. To explain rapid stiffening, the quark substructure of a baryon plays essential roles, already at density as low as a few times nuclear saturation density. We present an analytic model of the duality as a representative model of quarkyonic matter. We also argue the importance of non-perturbative power corrections which would substantially affect the high density constraints predicted by pQCD. Some results of QCD-like theories are briefly mentioned to address the recently proposed positivity conjecture of the trace anomaly.
