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.

Below are the latest papers in nuclear experiment research, curated to help you stay informed on the latest developments from the lab.
This paper presents measurements of near-threshold J/ photoproduction cross sections using the CLAS12 detector at Jefferson Lab, providing new experimental constraints on QCD models regarding the proton's gluonic structure and hadronic mass generation.
The ReD experiment extends direct measurements of argon nuclear recoil ionization yield into the critical 2–10 keV sub-keV regime, revealing enhanced yields at low energies and motivating the upgraded ReD+ phase to further advance low-mass WIMP dark matter searches.
This paper theoretically demonstrates the feasibility of observing mesic nuclei via the semi-exclusive C($p, dp$) reaction by utilizing the JAM transport model and Green's function method to show that detecting energetic protons from non-mesic absorption and forward-going deuterons is critically important for identifying bound states.
By combining a hybrid VDF+MIT equation of state with the AMPT-HC transport model and recent experimental directed flow data, this study constrains the hadron-quark phase transition to occur between 5 and 6 times nuclear saturation density and proposes the energy derivative of the mid-rapidity slope as a robust observable for identifying the QCD critical point.
This paper establishes a theoretical framework utilizing dihadron fragmentation functions and a newly introduced "EEC-DiFF" to bridge nonperturbative and perturbative regions of near-side energy-energy correlators, successfully reproducing experimental data in the free hadron and transition regimes through a first-of-its-kind fit.
This study employs a stochastic approach within the extended quantum molecular dynamics model to demonstrate that the peak position and width of the giant dipole resonance in Pb are highly sensitive to the symmetry energy and in-medium nucleon-nucleon cross sections, thereby offering a pathway to constrain the nuclear equation of state and confirming that a significant reduction of free cross sections in the medium is necessary to accurately reproduce experimental data.
This paper presents the latest results from the CUORE experiment, which has achieved leading limits on neutrinoless double beta decay in Te, and outlines the prospects for the upcoming CUPID upgrade that will utilize Mo-enriched crystals and particle identification to significantly enhance sensitivity to the Inverted Hierarchy of neutrino masses.
This paper reports the observation of partonic radial collectivity in Au+Au collisions at GeV through -differential flow fluctuations (), demonstrating that radial flow originates predominantly at the partonic stage via signatures such as mass ordering, meson-baryon separation, and robust Number of Constituent Quark scaling in central collisions.
This study utilizes PYTHIA8 to investigate two-particle differential balance functions in and low-multiplicity $pp$ collisions at TeV, revealing a systematic difference where the charge-dependent correlation width is narrower in events compared to $pp$ collisions, thereby offering insights into particle production mechanisms in small systems.
This paper demonstrates that kaon-decay-at-rest (KDAR) neutrinos enable coherent elastic neutrino-nucleus scattering measurements to extend beyond the strict coherent limit into the diffractive regime, offering a competitive and complementary method to electron scattering for precisely probing neutron skin thickness in various nuclei.
