When hadron-quark continuity is formulated in terms of a topology change at a density higher than twice the nuclear matter density (n0), the core of massive compact stars can be described in terms of quasiparticles of fractional baryon charges, behaving neither like pure baryons nor like deconfined quarks. Hidden symmetries, both local gauge and pseudo-conformal (or broken scale), emerge and give rise both to the long-standing “effective gA∗≈ 1” in nuclear Gamow–Teller (GT) transitions at ≲ n0 and to the pseudo-conformal sound velocity vpcs2/c2 ≈ 1/3 at ≳ 3n0. It is suggested that what has been referred to, since a long time, as “quenched gA” in light nuclei reflects what leads to the dilaton-limit gADL = 1 at near the (putative) infrared fixed point of scale invariance. These properties are confronted with the recent observations in GT transitions and in astrophysical observations.

重子物质中隐藏对称性的表现：从有限原子核到中子星

当强子-夸克连续性根据密度高于核物质密度两倍的拓扑变化来表述时(n0)，大质量致密恒星的核心可以用分数重子电荷的准粒子来描述，其行为既不像纯重子，也不像解限域夸克。隐藏的对称性，无论是局部规范还是伪等角（或破碎比例），都出现并产生了长期存在的“有效G一种*≈ 1”在核 Gamow-Teller (GT) 跃迁中 ≲ n0和伪共形声速v件2/C2 ≈ 1/3在 ≳ 3n0. 有人建议，长期以来一直被称为“淬火G一种” 在轻原子核中反映了导致膨胀极限的原因G一种深度学习 = 1在（假定的）红外固定尺度不变点附近。这些性质与最近在 GT 跃迁和天体物理观测中的观察有关。
