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 presents the development and testing of lightly doped amorphous silicon resistors designed for ultra-high radiopurity, mechanical stability, and cryogenic performance to be used in low-background detectors like the nEXO experiment.
This paper reports that the nuclear modification factor () for inclusive production in collisions at GeV is consistent with unity in the range of 4–12 GeV/, suggesting that cold nuclear matter effects are negligible in this specific kinematic region.
This paper demonstrates that including nonperturbative QED corrections—such as vertex, self-energy, and vacuum polarization effects—changes the calculated parity-violating asymmetry by less than one percent for various nuclei at both GeV and MeV energy scales.
This paper introduces a new thermodynamic state function to compute high-order temperature fluctuations in hot QCD matter, revealing that these fluctuations are significantly suppressed and exhibit negative skewness during the transition from a hadron resonance gas to a quark-gluon plasma due to the increased heat capacity of the latter.
Using data from the CMS detector at the CERN LHC, this study reports the first observation of suppressed charged-particle production in ultrarelativistic oxygen-oxygen collisions, evidenced by a nuclear modification factor below unity that supports the existence of parton energy loss in intermediate-sized nuclear systems.
This study utilizes an interacting boson model based on nuclear density functional theory to demonstrate that octupole correlations significantly influence low-lying states and two-neutron transfer intensities in rare-earth nuclei, successfully reproducing the experimental discontinuous changes near or 90 associated with shape phase transitions.
This paper presents ab initio Glauber theory calculations for high-energy nuclear scattering observables in p+12C, 12C+12C, and 6He+12C systems using variational Monte Carlo wave functions, demonstrating excellent agreement with experimental data and revealing that the cumulant expansion of the phase-shift function converges rapidly up to the second order.
This paper employs Bayesian inference within a unified framework to constrain the neutron star equation of state across hadronic, crossover, and quark phases, revealing that current multi-messenger data strongly limit low-to-intermediate density nuclear symmetry energy parameters while leaving high-density quark matter properties largely unconstrained until next-generation observations become available.
This paper demonstrates that accounting for hadrons produced via ion electromagnetic dissociation, which break experimental exclusivity vetos, resolves long-standing tensions between theoretical predictions and LHC measurements for exclusive muon pair and coherent production.
Using the AMPT model, this study demonstrates that while the nonlinear response coefficient grows dynamically during the evolution of relativistic heavy-ion collisions, the ratio of this coefficient between U+U and Au+Au systems remains stable across all stages, effectively isolating intrinsic initial-state geometric correlations to support experimental efforts in extracting high-order nuclear structure.
