Description
Protons and neutrons within atomic nuclei undergo intense, fleeting encounters driven by the strong, short-distance component of the nuclear force. These interactions generate close-proximity pairs known as short-range correlations (SRCs), which represent a fundamental yet poorly understood aspect of nuclear structure. While the properties of SRCs have been extensively characterized in cold nuclear matter, our understanding of their behavior under extreme high temperature conditions remains largely unexplored. Here, we introduce correlated nucleon configurations into relativistic heavy-ion collisions, treating quark–gluon plasma (QGP), a state of matter believed to have existed microseconds after the Big Bang, as a diagnostic tool. Our results show that these correlations induce substantial modifications to event-by-event geometry, which are quantitatively identified through higher-order moments of the transverse profile. Most significantly, the magnitude of SRCs exhibits a linear scaling with both nucleon number and average nuclear density, providing a striking and independent evidence for the scaling law in deep inelastic electron-scattering. By linking microscopic short-range configurations to the macroscopic QGP matter, these fndings reveal a universal emergence of short-range structural effects across vastly different energy scales from low energy electron-scattering to relativistic heavy-ion collisions.
