Nucl-Ex represents the dynamic frontier where scientists probe the fundamental building blocks of matter through high-energy experiments. By smashing particles together at incredible speeds or observing rare cosmic events, researchers uncover the forces that govern our universe and test the limits of our current understanding of physics.

At Gist.Science, we ensure these breakthroughs reach a broader audience by processing every new preprint in this field directly from arXiv. For each study, we provide both a clear, plain-language explanation of the core discoveries and a detailed technical summary for those seeking deeper insights. Below are the latest papers in nuclear experiment research, curated to help you stay informed on the latest developments from the lab.

Quantifying the Information Gain from Future High-Precision Radius Measurements for Identifying Twin Neutron Stars

This study employs Bayesian inference and information-theoretic measures to demonstrate that future neutron star radius measurements with a precision of approximately 0.2 km are sufficient to extract nearly all available information for identifying twin neutron stars, marking the point of diminishing scientific returns for distinguishing hadron-quark phase transitions.

Effect of the near-proton-emission threshold resonance in 11^{11}B on the branching ratio of beta-delayed proton emission from 11^{11}Be

This study employs Skyrme Hartree-Fock calculations within a potential model to demonstrate that the branching ratio of beta-delayed proton emission from 11^{11}Be is highly sensitive to the precise energy of a narrow resonance near the proton-emission threshold in 11^{11}B, reaching up to 10−510^{-5} and necessitating experimental confirmation of whether this resonance lies below 200 keV.

Measurement of the azimuthal anisotropy of charged particles in sNN=5.36\sqrt{s_{\mathrm{NN}}}=5.36 TeV 16^{16}O+16+^{16}O and 20^{20}Ne+20+^{20}Ne collisions with the ATLAS detector

This paper presents the first measurements of charged-particle azimuthal anisotropy coefficients (v2v_2–v4v_4) in 5.36 TeV 16^{16}O+16^{16}O and 20^{20}Ne+20^{20}Ne collisions with the ATLAS detector, revealing a clear v2>v3>v4v_2 > v_3 > v_4 hierarchy and enhanced elliptic flow in central neon collisions that aligns with theoretical predictions of prolate nuclear deformation.

Relativistic corrections and high-energy resummation for exclusive heavy quarkonium photoproduction

This paper computes the O(v2)O(v^2) relativistic correction to the high-energy resummed coefficient function for exclusive heavy quarkonium photoproduction, finding that while the correction itself is negligible at the physical mass scale, it significantly improves prediction robustness by partially canceling the factorization scale dependence of the leading-order relativistic correction.

Radiative corrections in neutral-current (anti)neutrino elastic scattering at GeV\text{GeV} energies I: Nucleon targets

This paper introduces radiative corrections within an effective field theory framework for neutral-current (anti)neutrino-nucleon elastic scattering at GeV energies, demonstrating that these corrections are comparable in magnitude to strange quark contributions and yield excellent agreement with BNL E734 and MiniBooNE experimental data.

Investigation of hadronic effects on resonance productions in small collision systems using the EPOS4 model

This study utilizes the EPOS4 model to demonstrate that hadronic interactions, specifically the competition between rescattering and regeneration, significantly modify resonance production yields and distributions in both small (pp, p-O) and large (O-O, Pb-Pb) collision systems at LHC energies, highlighting the critical role of the hadronic phase even in small systems.

Nuclear Charge Radius of 9^9Be from Muonic Atom Spectroscopy Using a Microcalorimeter

Using a metallic magnetic calorimeter to measure the 2p→1s2p\to1s transition energy in muonic 9^9Be with unprecedented precision, this study determines a nuclear charge radius of 2.5506(51) fm that is significantly more accurate than previous values and marks the first such determination via muonic x-ray spectroscopy with microcalorimeters.

Evidence for sequential Υ\Upsilon(nS) suppression in light ion collisions

This paper presents the first measurements of Υ\Upsilon(1S), Υ\Upsilon(2S), and Υ\Upsilon(3S) production in oxygen-oxygen and neon-neon collisions at sNN\sqrt{s_\mathrm{NN}} = 5.36 TeV, revealing a significant sequential suppression pattern where excited states are more strongly suppressed than the ground state, providing evidence for quark-gluon plasma formation in light ion collisions.
