Scale-invariant hidden local symmetry, topology change, and dense baryonic matter. II.

Abstract: Exploiting certain robust topological inputs from the skyrmion description of compressed baryonic matter with a scale-chiral symmetric Lagrangian, we predict the equation of state that is consistent with the properties of nuclear matter at the equilibrium density, supports the maximum mass of massive compact star ∼ 2M ⊙ and surprisingly gives the sound velocity close to the "conformal velocity" 1/ √ 3 at densities ∼ > 3n 0 . At the core of this result is the observation that parity-doubling occurs in the nucle… Show more

“…In the density regime n > n 1/2 , there is a topology change that drastically affects the IDDs at n = n 1/2 , parameters changed from those in n ≤ n 1/2 as explained in detail in [11]. It turns out that the results of the V lowk calculation for n > n 1/2 can be captured very well by the simple formula…”

“…In recent papers [11], it was proposed that both hidden local symmetry and hidden scale symmetry could emerge at densities relevant to ∼ 2 solar-mass neutron stars. As density increases it is natural to expect new degrees of freedom to be exited with the explicit emergence of those symmetries.…”

“…In this section, we present the results for the MKVOR* model with the universal meson mass scaling Φ m ( f ) = 1 − f , m = {σ, ω, ρ, φ}, in accordance with [11][12][13]. In the left panel of Figure 1, we show the particle concentrations and the scalar field f as functions of the total baryon densities.…”
