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 first results on baryon reconstruction from Ni+Ni collisions recorded by the mCBM demonstrator at SIS18, successfully validating the operational performance of the detector systems and the complete data chain for the upcoming high-rate CBM experiment at FAIR.
The CMS experiment reports the first measurement of charged-hadron pseudorapidity distributions in oxygen-oxygen collisions at = 5.36 TeV, revealing that while the particle density per participating nucleon in central collisions matches that of lead-lead collisions, the data exhibit deviations from simple scaling laws that highlight the significant role of collision geometry and finite-size effects in light ion systems.
This paper establishes a microscopic framework demonstrating that rotational symmetry restoration in relativistic heavy-ion collisions acts as a geometric low-pass filter that exponentially suppresses effective deformation modes, thereby reconciling the use of classically deformed geometries with the rotationally invariant quantum ground states of even-even nuclei.
This paper presents a novel theoretical framework combining deformed microscopic optical potentials with angular-dependent emission mechanisms to accurately predict the half-lives of oblate deformed proton emitters like Lu, revealing unprecedented angular emission phenomena and validating the model's predictive power for exotic nuclear decays.
This study employs ab initio Bogoliubov coupled cluster calculations to demonstrate that current chiral effective field theory interactions fail to simultaneously reproduce absolute charge radii, isotopic shifts, and the kink at Sn in the Tin isotopic chain, highlighting the need for improved theoretical methods and new experimental data to better constrain nuclear forces.
This paper presents a parameter-free microscopic framework that successfully predicts angular momentum distributions and photon multiplicities for neutron-induced fission of U and Pu, demonstrating that theoretical models are now quantitatively competitive with phenomenological approaches.
Using data from 102 million and 158 million decays collected by the Belle detector, researchers found no evidence for , , or dibaryon states and established the first 90% confidence-level upper limits on their production branching fractions at the level of –.
Using data from the ProtoDUNE-SP detector at CERN, this paper reports the first measurements of the total inelastic cross sections for -Ar and -Ar interactions in the sub-GeV energy regime, providing essential constraints for neutrino-argon interaction models critical to the upcoming DUNE experiment.
This paper reports experimental observations of thermal deuteron-deuteron fusion in deuterated titanium and palladium targets, confirming a yield plateau at low beam energies that supports the thermal spike model and highlights the critical roles of enhanced diffusion, electron screening, and threshold resonance in enabling fusion rates with potential astrophysical and commercial applications.
Using 2017 CMS data from proton-proton collisions at = 5.02 TeV, this study measures the angular structure of charm-tagged jets and finds that small-angle emission suppression is consistent with the dead-cone effect in late- grooming, while similar suppression in soft-drop selections is attributed to large-angle gluon splitting into charm quark-antiquark pairs.
