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 analytically demonstrates that the variation of the quark-gluon plasma volume in ultracentral collisions depends on initial density fluctuations and is negligible when total entropy scales with the mass number, thereby establishing that measurements of average transverse momentum can probe detailed nuclear structure and pre-equilibrium dynamics.
This paper proposes that quantum entanglement serves as a unifying foundation for statistical and high-energy physics, arguing that systems naturally evolve toward a Maximal Entanglement Limit where thermalization and probabilistic behaviors emerge from the geometry of high-dimensional Hilbert spaces without requiring ergodicity or classical randomness.
This paper presents a comprehensive review of an algebraic light-front model that provides a unified, symmetry-consistent description of the structure of pseudoscalar mesons across light, heavy-light, and heavy-heavy quark regimes, demonstrating how increasing quark mass drives a transition from broad, asymmetric momentum distributions to compact, symmetric configurations.
This paper presents recent PHENIX measurements of identified light hadrons and low-mass vector mesons across various collision systems and rapidities at RHIC to investigate final-state effects, hadronization mechanisms, and initial-state geometry through comparisons with empirical scaling laws and theoretical models.
This paper proposes a measurement program at the Electron-Ion Collider using polarized electron scattering on deuteron and He to directly constrain the axial two-body current and resolve current discrepancies in meson-exchange current models, which are critical for reducing uncertainties in long-baseline neutrino oscillation experiments.
This paper employs the non-equilibrium Green function method to investigate sub-barrier photo-induced fission in U, successfully reproducing experimental cross-section data and demonstrating that the first eigenchannel dominates the fission probability, thereby providing microscopic support for the Bohr-Wheeler transition-state picture.
The ALICE experiment reports the first observation of significant suppression in neutral pion () production in oxygen-oxygen (OO) collisions at LHC energies, providing strong evidence for parton energy loss in a hot medium that exceeds predictions based solely on cold nuclear matter effects.
The STAR Collaboration reports that hypertriton yields in central Au+Au collisions at RHIC energies between 3.2 and 27 GeV increase with decreasing energy but remain significantly below thermal model predictions, while a constant double ratio relative to light nuclei suggests a suppressed formation probability driven by weaker hyperon-nucleon interactions.
This paper challenges the recent MAMI collaboration's determination of the hypertriton binding energy by proposing that the observed sharp pion-momentum line instead originates from the weak decay of the ground state of hyperhelium-7 into lithium-7.
This paper presents precise mass measurements of neutron-deficient Cd isotopes using ISOLTRAP at CERN to determine the shell gap at and constrain the mass surface near Sn, revealing an enhancement of the shell gap towards the doubly magic nucleus that challenges state-of-the-art theoretical models.
