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.

Parity-transfer (16O,16F(0,g.s.))({}^{16}{\rm O},{}^{16}{\rm F}(0^-,{\rm g.s.})) reaction as a selective probe of isovector 00^- states in nuclei

This paper demonstrates that the parity-transfer (16O,16F(0,g.s.))({}^{16}{\rm O},{}^{16}{\rm F}(0^-,{\rm g.s.})) reaction serves as a highly selective probe for isovector 00^- excitations in nuclei, as evidenced by the clear observation and forward-peaked angular distributions of the known 00^- state and potential new structures in the 12B^{12}\mathrm{B} excitation spectrum.

Two-neutrino ββββ decay to excited states at next-to-leading order

This paper calculates next-to-leading order nuclear matrix elements for two-neutrino double-beta decay to excited states in key isotopes using the nuclear shell model, finding that while NLO corrections are typically small, they can become significant due to leading-order cancellations, and that nuclear deformation and seniority structure critically influence the predicted half-lives.

Observation of nuclear suppression in coherent Υ\Upsilon(1S) photoproduction off heavy nuclei at the LHC

The CMS experiment at the LHC reports the first observation of nuclear suppression in coherent Υ\Upsilon(1S) photoproduction off heavy nuclei, measuring a nuclear gluon suppression factor of RgPb0.55R_\text{g}^\text{Pb} \approx 0.55 at a high energy scale of μ2=22.4\mu^2 = 22.4 GeV2^2 and x103x \approx 10^{-3}.

Beam energy dependence of identified particle production in heavy-ion collisions using a parton-hadron string dynamics model

Using the parton-hadron string dynamics (PHSD) transport model, this study predicts transverse momentum spectra and yield characteristics of identified particles in Au+Au collisions across various beam energies and centralities, highlighting the critical roles of baryon stopping and strangeness production while providing theoretical context for current and future heavy-ion beam energy scan programs.

Particle background characterization and prediction for the NUCLEUS reactor CEννNS experiment

This paper presents a comprehensive prediction of particle-induced backgrounds for the NUCLEUS experiment at the Chooz nuclear power plant, demonstrating through environmental measurements and Geant4 simulations that the setup achieves sufficient background rejection to enable the detection of Coherent Elastic Neutrino-Nucleus Scattering with a signal-to-background ratio greater than one in the sub-keV energy range.

First Constraint on P-odd/T-odd Cross Section in Polarized Neutron Transmission through Transversely Polarized 139^{139}La

This paper presents the first constraint on time-reversal invariance violating effects in polarized neutron transmission through a transversely polarized 139^{139}La target by applying a density matrix formalism to existing data, yielding an upper limit of WT<15 eV|W_T|<15~\mathrm{eV} at 90% confidence level despite the data's lack of optimization for such observables.
