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.
This paper independently validates the IMRA computational framework for calculating product radionuclide activities in IAEA charged-particle monitor reactions, confirming overall consistency with IAEA reference data while identifying notable discrepancies for a subset of reactions induced by doubly charged particles.
This paper proposes that existing ultra-clean underground NaI dark matter detectors can search for galactic axions produced by carbon-burning stars via resonant absorption of 440 keV axions, potentially probing axion-nucleon couplings in a parameter space that remains viable despite existing astrophysical constraints.
This paper presents measurements of the exclusive deuteron electro-disintegration cross section at momentum transfers up to 3.5 , demonstrating that final state interactions are minimized at neutron recoil angles below where the data aligns best with CD-Bonn potential wave function calculations.
This paper reviews STAR Beam Energy Scan measurements of directed and elliptic flow in Au+Au collisions to investigate the energy-dependent breakdown and restoration of constituent quark number scaling, suggesting a transition in dominant degrees of freedom from hadrons to partons and providing insights into the QCD phase diagram and equation of state.
This study resolves a long-standing discrepancy in the to transition strength of Fe by using Coulomb-excitation measurements to demonstrate that previous lifetime data were overestimated due to outdated electronic stopping power models, thereby confirming the validity of shell-model predictions.
This paper introduces a novel algebraic modeling strategy for pion Generalized Parton Distributions that rigorously satisfies all QCD constraints, demonstrating through next-to-leading order calculations that gluons dominate the pion's response in deeply virtual Compton scattering at Electron Ion Collider kinematics.
This paper employs a Poincaré-covariant Dyson–Schwinger–Bethe–Salpeter framework to demonstrate that, despite the top quark's rapid weak decay, quantum chromodynamics predicts the existence of tightly correlated pseudoscalar and vector toponium bound states with masses near 345 GeV and minimal hyperfine splittings.
This study utilizes bremsstrahlung-induced photonuclear reactions on stable cadmium and tellurium isotopes to demonstrate that while incorporating isospin splitting in the combined model of photonucleon reactions successfully describes proton escape data at 17–23 MeV, significant unexplained discrepancies persist between theoretical predictions and experimental results for neutron emission channels in cadmium isotopes.
Using 9.95 kg·yr of exposure from the CUPID-0 experiment, researchers found no evidence of sterile neutrinos in the double beta decay of Se and established the most stringent upper limit to date on the active-sterile mixing probability () for a sterile neutrino mass of 0.7 MeV.
This paper investigates inclusive heavy meson ( and ) photoproduction in ultraperipheral $pPb$ and $PbPb$ collisions at LHC energies using the color dipole formalism with various unintegrated gluon distribution models, presenting first-time predictions for mesons and demonstrating that future experimental data will significantly constrain high-energy hadronic structure descriptions.
