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 reports the first experimental measurement of the Nb(n,) cross section, which resolves a two-decade discrepancy between stellar nucleosynthesis models and presolar grain data by confirming the production mechanism of Mo in low-mass AGB stars.
This paper introduces ALPHANSO, an open-source Python package that modernizes (,n) neutron source term calculations by incorporating updated nuclear data and offering a modular framework that matches or exceeds the accuracy of legacy tools like SOURCES-4C.
This paper presents a comprehensive survey and benchmark of nearly sixty pulse shape discrimination algorithms, demonstrating through standardized evaluation on two datasets that deep learning models often outperform traditional methods while providing an open-source toolbox to advance reproducibility in radiation detection research.
Using deuteron inelastic scattering in inverse kinematics with the CAT-M active target, researchers measured the isoscalar giant monopole resonance in Kr at 17 1 MeV to investigate the nuclear matter incompressibility and its isospin dependence.
Using lattice QCD at the physical point with the HAL QCD method, this study calculates S-wave kaon-nucleon potentials and scattering parameters, finding no evidence for the pentaquark resonance and suggesting that P-wave components dominate the scattering channel.
This paper demonstrates the highest-frequency mechanically driven Mössbauer resonance to date by efficiently coupling an enriched Fe film to a 97.9 MHz surface acoustic wave, thereby enabling coherent control of nuclear transitions through the generation of absorption sidebands well above the nuclear linewidth.
This paper reviews the current status of experimental searches for the chiral magnetic effect in relativistic heavy ion collisions, examining the observables and background mitigation techniques used while highlighting the lack of conclusive evidence due to significant background contributions and outlining future prospects.
This paper presents next-to-next-to-leading order (NNLO) QCD evaluations of proton and pion mass decompositions using gravitational form factors, comparing standard quark/gluon and trace-anomaly breakdowns with a novel twist-two/twist-four separation to demonstrate its advantages and reveal distinct parton-correlation behaviors between the two hadrons.
This paper proposes a novel algebraic framework for gamma-ray spectroscopy by modeling decay schemes as quivers and introducing a "coincidence algebra bundle" that extends path algebras to calculate coincidence probabilities for non-composable transitions.
This paper introduces a Bayesian protocol that combines full-spectrum template matching with probabilistic evidence evaluation to successfully identify single- and two-source neutron configurations from recoil and time-of-flight spectroscopy data with high statistical significance, even at low event counts.
