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 refines the theoretical upper bound on the central pressure-to-energy density ratio in neutron stars to approximately 0.385 by combining causality constraints with mass-sphere stability conditions within the IPAD-TOV framework, establishing a robust, EOS-insensitive probe for the microphysics of cold superdense matter.
This paper reports a room-temperature demonstration of a Cavallo electrostatic multiplier system that successfully generated approximately 255 kV from a 25 kV input in SF gas, validating its potential as a viable low-current, in situ high-voltage source for cryogenic precision measurements while highlighting electrode surface preparation and alignment as critical factors for future reliability.
This paper presents newly measured and revisited prompt fission neutron spectra for 233U, 235U, 239Pu, and 240Pu using double time-of-flight techniques, demonstrating that current evaluated data libraries are inadequate and highlighting the challenges in modeling these spectra across a wide range of incident neutron energies.
This paper reports the successful development and characterization of high-performance, radiopure LiMoO scintillating bolometers with excellent energy resolution, demonstrating their strong potential for use in rare-event search experiments.
The CROSS underground facility successfully tested upgraded detector suspensions with CdWO and LiMoO scintillating bolometers, achieving high energy resolution and radiopurity levels suitable for next-generation double-beta decay experiments while identifying specific noise sources for future mitigation.
The paper reports the successful development and characterization of high-performance, ultra-pure large-volume TeO bolometers for the CROSS double-beta decay experiment, achieved through directional solidification purification and validated by underground testing that demonstrated exceptional radiopurity and the potential for surface event tagging via pulse-shape discrimination.
This paper demonstrates that Neganov-Trofimov-Luke (NTL) assisted cryogenic light detectors achieve a signal-to-noise gain of approximately 9 and a baseline noise of ~10 eV, validating their viability for background reduction in future neutrinoless double-beta decay experiments like CUPID.
This paper details the design, construction, and validation of a nine-sector muon veto system for the CROSS experiment at the Canfranc underground laboratory, demonstrating its ability to reduce muon-induced background in the region of interest to an acceptable level for neutrinoless double-beta decay searches despite an 18% dead time.
This paper provides an introductory overview of nuclear structure, covering basic observables, a qualitative description of nuclear forces, and an outline of widely used models for interpreting experimental data in terms of interacting protons and neutrons.
This paper presents light hadron production measurements (, , p) from Au+Au collisions at fixed-target energies of --$4.5$ GeV using the STAR detector, utilizing blast-wave model analysis of transverse momentum spectra to study kinetic freeze-out properties and constrain the QCD equation of state in the high baryon density region.
