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 a global Bayesian analysis of unpolarized quark transverse-momentum-dependent parton distribution functions using Drell-Yan data at and accuracy, leveraging AI-driven functional form selection and machine-learning emulators to enable efficient Markov Chain Monte Carlo sampling and quantify uncertainties.
This paper combines the recent excess observed by the PADME experiment in positron annihilation with previous nuclear transition anomalies to strengthen the case for a common boson origin, yielding a refined mass measurement of that significantly reduces uncertainty compared to nuclear physics determinations alone.
The ATLAS experiment measured the differential cross sections of coherent exclusive production in ultraperipheral Pb+Pb collisions at TeV using 2023 data, finding results consistent with theoretical predictions but in tension with previous Run-2 measurements in the central rapidity region.
This paper reviews recent STAR experiment results on net-proton multiplicity fluctuations from RHIC BES-II collisions to search for the QCD critical point by comparing fourth-order cumulant and factorial cumulant ratios with non-critical theoretical models while addressing initial volume fluctuations and outlining future research directions.
Using chiral effective field theory interactions and the time-dependent coupled-cluster method, this study reveals that two-particle-two-hole excitations in O and Ca nuclei generate small-amplitude, fast, short-ranged, and stochastic density fluctuations.
This paper argues that the term "neutrinoless," which originated in 1953 and reflects a "sociology of suspicion," obscures the affirmative physics of matter creation by defining a fundamental process through absence rather than presence, necessitating a linguistic shift to "matter creation" to better align terminology with the radical nature of the laws being investigated.
This study extends multireference covariant density functional theory to successfully reproduce the low-energy structure of the odd-mass nucleus S, revealing a ground state dominated by an intruder prolate configuration, a high- isomer built on a prolate 1qp state, and a second excited state characterized by shape coexistence and -mixing.
This paper proposes that the anomalous suppression of ratios in neutron-deficient nuclei, which standard models fail to explain, arises from a low-lying mixed-symmetry collective excitation mode that bridges single-particle and collective dynamics.
This study validates olivine as a promising candidate for the "paleo-detector" technique by using STEM to characterize heavy-ion tracks at various depths without etching, confirming that observed changes in track continuity align with SRIM simulation predictions regarding the transition between electronic and nuclear stopping power.
This paper summarizes recent STAR collaboration results on heavy-ion collisions, covering topics such as jet and quarkonium modification in quark-gluon plasma, collective dynamics, low-energy and small-sized collisions, and vector meson production, while concluding with an outlook on the upcoming data-analysis era.
