Using the Antisymmetrized Molecular Dynamics model to analyze transverse momentum spectra of light clusters in central collisions at 56 and 140 MeV/nucleon, this study demonstrates that in-medium nucleon-nucleon scattering cross-sections experience a stronger reduction at the lower incident energy compared to the higher one.
This paper outlines Canada's Nuclear Emergency Response team's integration of emerging technologies, including uncrewed systems, advanced detectors, and high-performance computing, to enhance wide-area nuclear material search capabilities and improve the accuracy of source localization and error propagation.
This paper investigates the photoproduction of the exotic charged states and off nuclei using a collision model based on the nuclear spectral function, demonstrating that absolute and relative observables calculated for various internal structure scenarios (compact tetraquarks, molecules, and mixtures) are sensitive enough to distinguish their nature in future high-luminosity electron-ion collider experiments.
This paper presents a physics-based method for generating probability tables by calculating fluctuating cross sections using a Gaussian Orthogonal Ensemble -matrix model, validating the approach with U and Pu to show qualitative agreement with conventional Breit-Wigner formalism while accounting for statistical uncertainties and -matrix unitarity.
This study utilizes state-of-the-art 3D lattice covariant density functional theory to calculate uranium densities for hydrodynamic simulations of relativistic U+U collisions, revealing a tension between elliptic flow and transverse-momentum observables regarding effective quadrupole deformation while highlighting the challenges of constraining octupole deformation due to uncertainties in reference nuclear structures.
This paper investigates the decay as a probe for vorticity and spin alignment in heavy-ion collisions by deriving the general angular distribution of pions via interaction Lagrangian and helicity formalism, and subsequently calculating spin density matrix elements under local thermal equilibrium and blast wave models across different centrality classes.
This paper presents the first evaluation of virtual resonance contributions to charged-current (anti)neutrino-nucleon elastic scattering at GeV energies, demonstrating that these intermediate states induce permille-level corrections to the cross sections while exhibiting expected infrared behavior.
This paper resolves the ambiguity in mixing between nonlocal gluon and quark bilinear operators by demonstrating that dimensional regularization provides a consistent prescription for handling singularities at zero separation, ensuring agreement between coordinate and momentum space results and compatibility with lattice QCD extractions.
This paper pays tribute to the late Toshimitsu Yamazaki by highlighting his pioneering work on deeply bound pionic states and kaonic nuclei, while also presenting recent findings that confirm a deeply bound dibaryon is not excluded by hypernuclei observations but remains too short-lived to be a dark matter candidate.
This paper presents the first measurement of transverse momentum-dependent radial flow fluctuations in Pb+Pb collisions using the ATLAS detector, providing experimental evidence for the collective nature of radial flow and demonstrating its sensitivity to the quark-gluon plasma's bulk viscosity.
