Below are the latest papers in nuclear experiment research, curated to help you stay informed on the latest developments from the lab.
This paper demonstrates for the first time that neural simulation-based inference (NSBI) can effectively constrain proton parton distribution functions using high-dimensional, unbinned LHC data, achieving significantly improved precision over traditional binned analyses by fully exploiting statistical power and reducing reliance on coarse uncertainty approximations.
This study determines the properties of key resonances in Ne using experimental angular distributions and theoretical modeling to refine the F()O reaction rate, revealing that previous estimates significantly underestimated the associated uncertainties for classical nova positron production.
The BM@N experiment at JINR measured transverse momentum spectra and rapidity distributions of hyperons produced in carbon-nucleus collisions at 4.0A and 4.5A GeV, comparing the results with various theoretical transport models and existing experimental data.
This paper presents a data-driven comparative analysis of various statistical distance metrics and normalizing functions using electron and photon events from a decaying Kr-83 isotope to evaluate the stability of a dimensionless Parameter of Interest under different conditions.
This review article examines the theoretical foundations and experimental strategies for searching for neutrinoless double beta decay, summarizes current results and detection techniques, and outlines future technological advances required to achieve the sensitivity necessary to confirm this rare phenomenon.
This study utilizes a second-order relativistic viscous hydrodynamic framework to quantify the contributions of thermal vorticity and evolving magnetic fields to the global spin polarization of hyperons, finding qualitative agreement with recent ALICE measurements at TeV energies and offering new insights into the vortical structure of QCD matter.
This paper proposes that neutron-nucleus interactions with anomalously large scattering lengths could enable the observation of the Efimov effect in nuclear systems, specifically investigating the potential for B to exist as a B-- Efimov trimer.
This study utilizes the AT-TPC within the SOLARIS solenoid to perform the first high-luminosity inverse kinematics Be() transfer reaction measurement, determining spectroscopic factors for Be states up to 3.40 MeV and providing evidence through comparison with NCCI calculations that the 3.40 MeV state has positive parity, consistent with it being the second excited state of the ground-state rotational band.
The STAR experiment at RHIC provides strong evidence for jet quenching in oxygen-oxygen collisions at GeV by observing a significant 20% suppression of high-transverse-momentum hadron and jet yields in high-event-activity collisions, indicating the formation of a quark-gluon plasma even in small collision systems.
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.
