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.
Motivated by the ATOMKI anomalies, this study employs the Gaussian Expansion Method to predict X17-induced Lamb shifts and hyperfine splittings in muonic atoms up to Z=15, identifying specific isotopes like muonic deuterium, helium ions, and silicon-29 as promising probes to distinguish between vector and pseudoscalar fifth-force mediators.
This study provides a comprehensive comparison of coupled-cluster formulations based on symmetry-broken reference states and equation-of-motion techniques, demonstrating that both approaches yield consistent descriptions of bulk nuclear properties across calcium and nickel isotopic chains when using chiral effective field theory interactions.
This paper employs cluster effective field theory, fitted to recent experimental data from the LUNA and JUNA collaborations, to calculate the factor of the C(,)O reaction at low energies and extrapolate it to the Gamow peak relevant for low-mass AGB stars, identifying the near-breakup threshold state of O as the primary source of uncertainty.
Using the three-fluid dynamics model, this study calculates global polarization in Au+Au collisions at high baryon densities (3–9 GeV), successfully reproducing STAR data at 3 GeV and predicting a broad maximum in polarization around 3–3.9 GeV while analyzing the specific contributions of thermal vorticity, meson fields, thermal shear, and the spin-Hall effect.
This study reports the direct measurement of lifetimes for the and states in using the fast timing technique with a CeBr detector array, and compares the resulting reduced transition probabilities with large-basis shell model and interacting boson model calculations.
The TRIUMF collaboration reports initial successful production of ultracold neutrons from a new spallation-driven superfluid helium-4 source, with results aligning with simulations and indicating the facility is on track to achieve its ultimate goals for a high-precision measurement of the neutron electric dipole moment once the cold moderator system is completed.
Using a three-fluid dynamics model with a crossover equation of state, this paper predicts a non-monotonic evolution of proton directed flow in Au+Au collisions between 4.5 and 7.7 GeV, characterized by a sign change and minimum at 7.2 GeV that signals the onset of the transition to quark-gluon plasma.
This paper presents general methods for extracting transverse single-spin asymmetries using both binned and unbinned maximum likelihood approaches, specifically designed to address experimental challenges such as time-varying polarization, unequal spin-state luminosities, and the need for background subtraction and kinematic unfolding.
This report synthesizes the outcomes of the 2025 EIC-France Workshop, outlining theoretical advancements and strategic priorities for the French hadron-physics community, with a specific focus on immediate opportunities in inclusive diffraction and quarkonium production alongside longer-term goals in pion structure and exclusive three-body final states.
This study presents the first measurement of charged-particle nuclear modification factors in neon-neon collisions and systematically compares them with oxygen-oxygen, xenon-xenon, and lead-lead data to demonstrate that charged-particle suppression scales with nuclear size and is well-described by energy loss models rather than initial-state nuclear effects.
