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 the design, current status, and future upgrade plans for the CERES experiment, a dedicated cryogenic setup developed to directly measure and characterize the position-dependent systematic effects on energy scale and resolution in TeO bolometers used for rare event searches.
This paper presents recent CMS measurements at the LHC that extract the squared speed of sound of hot QCD matter from ultra-central PbPb collisions, yielding a value of at which aligns well with lattice-QCD predictions, alongside complementary studies in pPb collisions to probe quark-gluon plasma signatures in smaller systems.
This paper describes the installation of a large, versatile vacuum chamber at the NIST Center for Neutron Research to stabilize perfect-crystal neutron interferometry against environmental fluctuations and enable cryogenic sample studies, demonstrated by the first successful measurement of a Ni60Cu40 sample cooled from 300 K to 4 K.
This paper presents a unified open quantum system framework based on the Lindblad equation to describe both the suppression and thermal recombination of charmonium and bottomonium states in ultrarelativistic heavy-ion collisions undergoing Bjorken expansion.
This paper demonstrates that applying a specific non-unique coordinate transformation using experimentally derived deformation parameters to Bohr's quasi-molecular model successfully reproduces the emergence of cluster formation and characteristic shapes in light nuclei, such as B and Ne, while providing a physical interpretation of triaxiality through the superposition of multiple intrinsic configurations.
Researchers at the Baksan Neutrino Observatory have achieved the first detection of the single beta decay of Zr using a low-background HPGe detector and enriched zirconium samples, measuring its half-life to be approximately years while also observing the subsequent decay of the daughter nucleus Nb.
This paper proposes and theoretically validates a new method to observe quark effects in nuclei by analyzing in-medium modified nucleon magnetic moments through bremsstrahlung spectra in proton-nucleus scattering, specifically highlighting the potential of using ratios between carbon isotopes like C and C to isolate these effects.
This study employs an \textit{ab initio} valence space in-medium similarity renormalization group method to investigate quantum entanglement measures, such as proton-neutron entanglement entropy and mutual information, revealing their critical role in characterizing the structure and correlations within the island of inversion region for neutron-rich Ne, Mg, and Si isotopes.
This paper presents the first Bayesian extraction of the trace anomaly of cold dense matter from collective flow observables in heavy-ion collisions, demonstrating a quantitative agreement with independent astrophysical constraints from neutron stars and establishing a consistent macroscopic bridge between terrestrial and cosmic dense-matter environments.
This paper utilizes the MC-CGC event generator to demonstrate that LHCb data favors HERA-constrained initial conditions for the rcBK evolution equation and that the dense-dense factorization framework better describes mid-rapidity particle production than the dilute-dense DHJ approach, while also providing predictions for future ALICE FoCal measurements.
