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 an analytical framework using a square-well potential to model short-range nucleon-nucleon interactions, providing a more accurate tool for proton-proton femtoscopy than the standard Lednicky-Lyuboshits approximation, especially for small source sizes.
This study investigates incomplete fusion in the C+Ir reaction at 5–7 AMeV using the stacked-foil activation technique, finding that the incomplete fusion fraction increases with energy and entrance-channel parameters like mass asymmetry and Coulomb factor, while also demonstrating that projectile breakup suppresses complete fusion relative to standard theoretical models.
By analyzing the Lund jet plane of high-energy jets in PbPb collisions compared to pp collisions, this study finds no significant difference in the angular distribution of high- emissions, suggesting that these early parton emissions occur before the jet interacts substantially with the quark-gluon plasma.
This paper reviews how density-dependent optical potentials can fit -hypernuclear binding energies using an attractive interaction and a repulsive interaction, the latter of which provides a strength consistent with resolving the hyperon puzzle.
This paper investigates the sensitivity of multi-particle symmetric and asymmetric cumulants to shear and bulk viscosities, resonance decays, and hadronic interactions in Au+Au collisions at = 200 GeV using a hybrid hydrodynamic-transport model.
The XENONnT experiment has reported the first measurement of nuclear recoils from solar B neutrinos using coherent elastic neutrino-nucleus scattering, providing a solar neutrino flux and cross section consistent with Standard Model predictions.
Researchers observed a broad -wave resonant state in He at 1.28(1) MeV using two-body invariant-mass spectroscopy following the knockout reaction of Li at approximately 250 MeV/nucleon.
This paper presents a parameter-free method to determine the chiral phase transition temperature and critical exponent in (2+1)-flavor QCD by constructing ratios of an improved, renormalized order parameter, with initial numerical results obtained on lattices using staggered fermions.
By combining quasi-elastic scattering measurements with coupled-channels and shell-model calculations, this study reveals that while Si has a distinct oblate ground state, the addition of two neutrons in Si leads to a sudden structural change where the nucleus lacks a well-defined intrinsic shape, suggesting the presence of ground-state shape fluctuations.
This paper extends spherical coupled-cluster theory to open-shell nuclei with two nucleons removed, validating the method against experimental data for oxygen and calcium isotopes while demonstrating high accuracy for binding energies and excited states but noting an underestimation of electric dipole polarizabilities.
