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 utilizes Fourier-Bessel transformations of exclusive meson production cross sections from photon-proton collisions to reveal that the proton's baryon number is concentrated in a transverse radius of 0.33–0.53 fm, which is significantly smaller than the proton's charge and mass radii.
This paper identifies fluorine-based compounds, particularly octafluoropropane, as optimal targets for measuring subleading axial-vector contributions in coherent elastic neutrino-nucleus scattering, demonstrating that such experiments could determine the axial coupling at the level and probe spin-dependent new physics.
The paper proposes a novel nuclear interferometer utilizing the thorium-229 clock transition to detect ultra-light dark matter, offering enhanced sensitivity to variations in fundamental constants and the QCD sector that could complement and surpass existing terrestrial clock experiments.
A high-sensitivity search for neutron-to-mirror-neutron oscillations conducted at the PSI UCN source found no evidence of anomalous neutron losses, thereby excluding 99.98% of the previously claimed parameter space and establishing new limits on the oscillation time constant.
This paper derives the one-point energy correlator for deep inelastic scattering in the small- limit using the Color Glass Condensate framework, demonstrating that it serves as a clean, nonperturbative-free probe of gluon saturation dynamics with significant nuclear suppression effects relevant to the future Electron-Ion Collider.
This paper presents a unified, physics-informed framework for predicting the critical electric field required for internal charge amplification in cryogenic germanium at 77 K and 4 K, bridging single-free-flight bounds with detailed scattering mechanisms to provide closed-form design formulas and a practical calibration workflow for optimizing detector performance.
This paper proposes a method to "unshadow" the constituent quark number scaling of harmonic flow by disentangling spectator shadowing effects from the particle emitting source, thereby offering a refined framework to interpret recent STAR measurements and future CBM data regarding the Quark-Gluon Plasma phase transition.
This study demonstrates that the charge-weak form factor difference in Ca and Zr is highly sensitive to the isovector spin-orbit interaction due to specific shell structures, whereas Pb and Ni remain insensitive, thereby guiding a strategic approach to use parity-violating electron scattering on these distinct nuclei to separately constrain the isovector spin-orbit strength and the symmetry energy slope.
This paper extends the theoretical and phenomenological analysis of recent NA61/SHINE collaboration findings by establishing the conceptual and analytical foundations of isospin symmetry and proving that, under charge-symmetry invariant initial conditions, the mean multiplicities of charged and neutral kaons should be equal, thereby highlighting the significance of the observed violation.
This study demonstrates that multiparticle azimuthal correlations in central Ru+Ru and Zr+Zr collisions at 200 GeV are sensitive probes of nuclear deformation and neutron skin thickness, offering a robust method to disentangle nuclear structure effects with minimal dependence on shear viscosity.
