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.

Effects of isovector spin-orbit interaction on the charge-weak form factor difference in 48^{48}Ca, 208^{208}Pb, 90^{90}Zr and 62^{62}Ni

This study demonstrates that the charge-weak form factor difference in 48^{48}Ca and 90^{90}Zr is highly sensitive to the isovector spin-orbit interaction due to specific shell structures, whereas 208^{208}Pb and 62^{62}Ni remain insensitive, thereby guiding a strategic approach to use parity-violating electron scattering on these distinct nuclei to separately constrain the isovector spin-orbit strength and the symmetry energy slope.

Evidence of isospin-symmetry violation in high-energy collisions of atomic nuclei: Theoretical and Phenomenological considerations

This paper extends the theoretical and phenomenological analysis of recent NA61/SHINE collaboration findings by establishing the conceptual and analytical foundations of isospin symmetry and proving that, under charge-symmetry invariant initial conditions, the mean multiplicities of charged and neutral kaons should be equal, thereby highlighting the significance of the observed violation.

Disentangling nuclear structure through multiparticle azimuthal correlations in high-energy isobar collisions

This study demonstrates that multiparticle azimuthal correlations in central 96^{96}Ru+96^{96}Ru and 96^{96}Zr+96^{96}Zr collisions at 200 GeV are sensitive probes of nuclear deformation and neutron skin thickness, offering a robust method to disentangle nuclear structure effects with minimal dependence on shear viscosity.

Identifying αα-cluster configurations in 20^{20}Ne via ultracentral Ne+Ne Collisions

This paper proposes using normalized symmetric cumulants and Pearson coefficients derived from ultracentral Ne+Ne collisions at the LHC, combined with Brink model calculations and hydrodynamic simulations, to distinguish between competing 20^{20}Ne cluster configurations (5α\alpha versus α\alpha+16^{16}O) and probe nuclear structure transitions.

Next Generation Ta-STJ Sensor Arrays for BSM Physics Searches

To address systematic calibration discrepancies caused by resistive crosstalk and laser instability in Phase-III, the BeEST experiment's Phase-IV introduces redesigned STJ sensor arrays with individual ground wires and a more stable UV laser, successfully eliminating artifacts while maintaining high energy resolution for future BSM physics searches.

Leptonic first-row correlation and unitarity waiting for further JUNO tests

The paper conjectures a remarkable correlation among the first-row elements of the lepton mixing matrix, ∣Ue1∣2=2(∣Ue2∣2+∣Ue3∣2)|U_{e1}|^2 = 2(|U_{e2}|^2 + |U_{e3}|^2), which remains consistent with unitarity limits and is currently supported by JUNO and Daya Bay precision measurements at nearly the 1σ1\sigma confidence level.

Automated event generation for S-wave quarkonium and leptonium production in NRQCD and NRQED

This paper presents an extension of the MadGraph5_aMC@NLO framework that enables automated leading-order calculations for S-wave quarkonium and leptonium production within NRQCD and NRQED formalisms, offering seamless integration with Beyond the Standard Model scenarios and highlighting the necessity of careful theoretical analysis beyond simple velocity-scaling rules.

Calibration of an Irradiated Prototype for the EIC Zero-Degree Calorimeter

This study demonstrates that a prototype Electron-Ion Collider Zero-Degree Calorimeter, after being irradiated to simulate one year of full-luminosity operation, can be successfully calibrated on a channel-by-channel basis using cosmic-ray data, maintaining a sufficient signal-to-noise ratio despite significant and non-uniform radiation damage to its SiPMs.
