Bridging the Gap: Connecting Atomic Nuclei to Their Quantum Foundations

Fredrick Olness

Abstract

We extend the QCD Parton Model analysis by employing a factorized nuclear structure model that explicitly accounts for both individual nucleons and correlated nucleon pairs. This novel framework establishes a paradigm that directly links the nuclear physics description of matter (in terms of protons and neutrons) to the particle physics schema (in terms of quarks and gluons). Our analysis of high-energy data from lepton Deep-Inelastic Scattering, Drell-Yan, and W/Z production simultaneously extracts the universal effective distribution of quarks and gluons inside correlated nucleon pairs, and their nucleus-specific fractions. The successful extraction of these universal distributions marks a significant advance in our understanding of nuclear structure, as it directly connects nucleon-level and parton-level quantities.

Figures (1)

  • Figure 1: (a) Comparison of nuclear structure parameters $C_p^A$, $C_n^A$, and $(N/Z)C_n^A$ values for the baseSRC fit. The solid lines represent logarithmic fits to the corresponding quantities. We show uncertainties only for the $C_p^A$, but errors for other quantities are of similar size. (b) Comparison of $C_p^A$ values for the baseSRC fit and the SRC abundances extracted from quasi-elastic (QE) CLAS:2005olaFomin:2011ngSchmookler:2019nvf data and Quantum Monte Carlo (QMC) Cruz-Torres:2019fum nuclear calculations. The logarithmic fits for baseSRC and pnSRC are also shown.
