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.

A relativistic mechanism for the enhanced isovector spin-orbit interaction suggested by parity-violating electron scattering experiments

This paper proposes that an enhanced isovector tensor coupling within covariant density-dependent point-coupling energy density functionals naturally induces a strong isovector spin-orbit interaction, offering a relativistic mechanism to simultaneously resolve the tensions between PREX-II and CREX parity-violating electron scattering data while maintaining accurate descriptions of nuclear properties.

The Silicon Tracking System of the E16 experiment at J-PARC: construction, installation and commissioning in beam test experiments

This paper details the construction, characterization, commissioning, and beam test performance of 15 Silicon Tracking System modules, originally developed for the FAIR-CBM experiment, which were installed and operated in the J-PARC E16 experiment to search for chiral symmetry restoration signatures.

Evidence for parton energy loss in oxygen$-$oxygen collisions at sNN=5.36\mathbf{\sqrt{s_{\rm NN}}=5.36} TeV

This paper presents the first unambiguous evidence of parton energy loss (jet quenching) in oxygen-oxygen collisions at sNN=5.36\sqrt{s_{\rm NN}}=5.36 TeV, demonstrated by a significant suppression of the double ratio ROO/RpOR_{\rm OO}/R_{\rm pO} at a 4.9σ4.9\sigma level that cannot be explained by cold nuclear matter effects alone.

Probing flavor effects in the QCD parton shower using D0\mathbf{{\rm D}^0}-tagged jet angularities in proton$-$proton collisions at s=5.02\mathbf{ \sqrt{s} = 5.02} TeV

The ALICE Collaboration presents the first measurements of D0{\rm D}^0-tagged jet angularities in proton-proton collisions at s=5.02\sqrt{s} = 5.02 TeV, providing evidence for the QCD dead-cone effect by demonstrating that charm-quark-initiated jets exhibit suppressed collinear radiation compared to inclusive jets, thereby establishing a crucial baseline for future heavy-ion studies.

Precision mass measurements of multistrange baryons and their antiparticles

This paper reports high-precision measurements of the masses of the Ω\Omega^- and Ξ\Xi^- baryons and their antiparticles using ALICE data from LHC proton-proton collisions, achieving fractional uncertainties of approximately 60 parts per million to establish new benchmarks for strange-baryon spectroscopy, test CPT invariance, and significantly reduce scale uncertainties in lattice QCD calculations.

Probing Strange-Quark Hadronization via (Multi-)Strange Hadron Multiplicity Distributions in Small Collision Systems with ALICE

The ALICE collaboration presents the first event-by-event measurement of probability distributions for strange-hadron multiplicities in proton-proton collisions at 5.02 TeV, providing a novel test of strangeness production mechanisms that extends beyond mean yields to probe large imbalances between strange and non-strange content.

Measurements of charged-particle pseudorapidity and transverse momentum distributions in O+O and Ne+Ne collisions at sNN=5.36\sqrt{s_{_\text{NN}}} = 5.36 TeV with the ATLAS detector

The ATLAS experiment presents measurements of charged-particle pseudorapidity and transverse momentum distributions in O+O and Ne+Ne collisions at sNN=5.36\sqrt{s_{_\text{NN}}} = 5.36 TeV, characterizing these observables across various centrality intervals and comparing the results with hydrodynamic calculations.

Observation of centrality-dependent dijet transverse momentum imbalance in O+O and Ne+Ne collisions at sNN\sqrt{s_{NN}} = 5.36 TeV with the ATLAS detector

The ATLAS experiment observed a centrality-dependent dijet transverse momentum imbalance in O+O and Ne+Ne collisions at sNN\sqrt{s_{NN}} = 5.36 TeV, providing evidence for medium-induced partonic energy loss and establishing a new regime for studying quark-gluon plasma effects in small collision systems.
