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.

Below are the latest papers in nuclear experiment research, curated to help you stay informed on the latest developments from the lab.
This paper proposes a novel method using cryogenic microcalorimeters to perform precision muonic x-ray spectroscopy of light transition elements, aiming to reduce the uncertainty in their absolute electric quadrupole moments by an order of magnitude to significantly advance nuclear structure studies and quantum chemistry benchmarks.
This paper presents a model for coherent Deeply Virtual Compton Scattering on polarized He at the Electron-Ion Collider, demonstrating that early data will precisely constrain the unpolarized Compton Form Factor while requiring significantly higher luminosities to meaningfully constrain the polarized component, alongside an analysis of the necessary far-forward detector capabilities for tagging intact nuclei.
This paper applies the Confined beta-Soft (CBS) rotor model to systematically calculate and compare ground-state band energies, B(E2) transition rates, and beta-band excitations of even-even rare-earth nuclei with experimental data, while also providing predictions for unmeasured observables to guide future research.
This paper proposes a method to reconstruct the gluon spatial distribution in high-energy nuclei by measuring the projected momentum transfer distribution perpendicular to the electron scattering plane to mitigate resolution effects and utilizing the angular distribution of vector meson decay products to statistically suppress incoherent backgrounds.
This study employs state-of-the-art full configuration-interaction quantum Monte Carlo (FCIQMC) to perform exact calculations of infinite nucleonic matter, revealing that symmetric nuclear matter is strikingly strongly correlated and challenging the validity of previous many-body expansion truncations.
This paper proposes that precise measurements of total charm production in heavy-ion collisions, when combined with improved calculations of initial hard scatterings, can serve as a signature to infer properties of the pre-equilibrium stage, despite current theoretical uncertainties.
This paper presents a general framework for subtracting nonflow effects from multi-particle cumulants in small collision systems by leveraging scaling and dipolar flow estimators, thereby enabling the systematic quantification of collective flow at particle multiplicities previously inaccessible due to uncontrolled nonflow residuals.
This paper proposes a novel invariant-mass observable using the resonance to experimentally distinguish between nucleon coalescence and statistical thermal models for deuteron formation at the LHC, demonstrating that a specific resonance peak in the proxy mass spectrum emerges exclusively in the coalescence scenario.
This paper demonstrates through simulations and experiments at two research reactors that continuous-signal neutron noise analysis, utilizing pulse-shape deconvolution or detector pairs, effectively overcomes the dead-time and pile-up limitations of traditional pulse-counting to provide unbiased kinetic parameter estimation at high detection rates.
Using the - fast-timing technique with the VENTURE array at VECC, Kolkata, researchers measured the lifetimes of low-lying negative-parity states in Gd to determine that their transition strengths are strongly hindered, providing evidence for weak dipole strength in octupole bands.
