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 study employs a hybrid approach alongside pure hadronic and string models to predict collective effects in upcoming O-O and Ne-Ne collisions at the LHC, aiming to determine the onset of quark-gluon plasma formation in small collision systems by comparing hydrodynamic and non-hydrodynamic evolutions.
This paper reports the first production of gas-centrifuge-enriched Zr samples and their subsequent low-background investigation, which established a new, stringent half-life limit of years for the double beta decay of Zr to the excited state of Mo.
Using 2023 ALICE data from ultra-peripheral Pb–Pb collisions at TeV, this paper presents forward rapidity measurements of coherent J/ and (2S) photoproduction and exclusive dimuon production, revealing significant nuclear shadowing effects in quarkonium production and highlighting the sensitivity of dimuon measurements to photon flux modeling near the nuclear radius.
This paper proposes a model-independent dark photon search strategy using spectral shape differences in photon production from decays, demonstrating via GEANT4 simulations that a 1 GeV proton beam with tungsten foils could probe previously unexplored parameter space for dark photons with predominantly invisible decays.
This paper computes all possible medium-induced single-scattering emission kernels for an energetic virtual quark traversing a nuclear environment at next-to-leading order and next-to-leading twist, incorporating heavy-quark mass effects, Glauber quark and gluon interactions, and coherence effects to derive four distinct collisional scattering kernels with full phase factors and gradient expansions.
This paper employs a Bayesian framework with a two-dimensional Gaussian process to quantify chiral effective field theory uncertainties in the equation of state for asymmetric nuclear matter up to twice saturation density, thereby constructing consistent models for the inner crust and outer core of neutron stars.
This paper presents the performance evaluation of the new PISTA silicon-telescope array coupled with the VAMOS++ magnetic spectrometer, demonstrating its capability to achieve high-resolution particle identification and excitation energy reconstruction (800 keV FWHM) for studying fission processes induced by multi-nucleon transfer reactions in inverse kinematics.
The ICESPICE demonstrator, a modular mini-orange spectrometer developed at Florida State University, successfully enables particle/gamma-electron coincidence measurements for low-energy nuclear structure studies, as validated by commissioning tests and its first in-beam application with the Super-Enge Split-Pole Spectrograph.
This paper reports the first measurement of the state lifetime in Sn using thermal-neutron capture, where the observed enhanced transition strength provides compelling evidence for multiple shape coexistence, a finding corroborated by theoretical calculations predicting three distinct nuclear shapes in the Sn isotopes.
This paper outlines a proposed physics program using the upgraded CLAS12 detector to explore the three-dimensional quark and gluon structure of the nucleon through precision measurements of Double Deeply Virtual Compton Scattering, Timelike Compton Scattering, and near-threshold production via di-muon electro- and photoproduction.
