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.

Energy-energy correlators in p-Pb collisions at sNN=5.02\sqrt{s_{\rm NN}} = 5.02 TeV

The ALICE experiment reports the first measurement of the two-point energy-energy correlator (EEC) inside charged-particle jets in p-Pb collisions at sNN=5.02\sqrt{s_{\rm NN}} = 5.02 TeV, revealing a modification relative to pp collisions characterized by suppression at small angles and enhancement at large angles, which provides new constraints on cold nuclear matter effects relevant for understanding jet-structure modifications in heavy-ion collisions.

Observation of a dominant 0f7/2\boldsymbol{0f_{7/2}} neutron configuration in the 32\boldsymbol{^{32}}Si Jπ=5\boldsymbol{J^{\pi}=5^-} isomeric state

This study confirms that the Jπ=5J^{\pi}=5^- isomeric state in 32^{32}Si possesses a dominant single-neutron ν0f7/2\nu0f_{7/2} configuration and reveals that the hindrance of its decay to the 33^- state arises from a lack of participation by both protons and neutrons rather than differences in neutron structure overlap.

Electric dipole strength in $sd$-shell nuclei from small-angle proton scattering

This study presents new total photoabsorption cross sections for several N=ZN=Z $sd$-shell nuclei derived from small-angle 295 MeV proton scattering, comparing the results with artificial neural network predictions and configuration-interaction shell-model calculations to validate the latter's ability to describe fragmented electric dipole strength for applications in ultrahigh-energy cosmic ray research.

Peak-Based Nuclide Identification in HPGe γ\gamma-Spectrometry with Machine Learning and SHAP

This paper presents a supervised machine learning approach for automating nuclide identification in HPGe gamma spectrometry, which achieves a superior F1 score of 0.97 compared to traditional software (0.84) and utilizes SHAP values to confirm that the model relies on physically relevant photopeaks for its predictions.
