This paper identifies the origin of perturbative instabilities in NNLO QCD corrections to quarkonium production and decay within non-relativistic QCD and proposes a simple remedy involving soft contributions that significantly improves convergence and agreement with experimental data for S-wave color-singlet processes.
This paper reviews recent experimental and theoretical advances in understanding dineutron clusters within neutron-rich nuclei, highlighting evidence from halo nuclei and unbound systems, the role of few-body theories in interpreting decay processes, and the potential connection to four-neutron clusters and universal few-body physics.
This paper introduces a physics-informed self-supervised framework that jointly learns detector calibration parameters and task-specific predictions from raw measurements by exploiting known physical constraints to generate pseudo-labels, thereby enabling autonomous calibration and monitoring of scientific instruments without requiring expert intervention or manually labeled data.
Heavy-ion collisions serve as a crucial tool for constraining the nuclear equation-of-state at high densities, offering insights that complement multi-messenger astronomy observations of neutron stars, while future advancements in experimental precision and transport modeling are essential to further elucidate the symmetry energy and related nuclear phenomena.
Using antisymmetrized molecular dynamics combined with the generator coordinate method, this study constrains the oblate-prolate shape mixing amplitudes in Si by reproducing experimental observables, revealing a dominant oblate component in the ground state and establishing an upper limit for the inter-band E0 transition strength.
This paper presents a femtoscopic analysis of proton-proton correlations in minimum bias $pp$ collisions at TeV using a high-luminosity ALICE dataset, which enables the first simultaneous measurement of the hadron-emitting source size's dependence on multiplicity and transverse mass, revealing a distinct multiplicity trend compared to Pb-Pb collisions and demonstrating the robustness of the results across various nucleon-nucleon interaction models.
This paper reveals that systematic shifts in inferred neutron star equation of state parameters with varying observational precision arise from nonlinear filtering of radius measurements through previously unidentified, nearly universal inverse mappings between stellar radius and empirical EOS parameters.
This study reports new independent half-life measurements for Sn, Sn, Sn, and Sn produced via photon activation, confirming most existing nuclear data but revealing a statistically significant discrepancy for the Sn isomer that warrants further investigation.
This paper demonstrates that multi-particle cumulant methods, applied to simulated heavy-ion collision data combining a hydro-like background with Pythia-8 jets and unfolded via Bayesian techniques, can accurately reconstruct differential jet azimuthal anisotropies to provide insights into high- dynamics.
This study investigates the low-lying excitations of the odd-odd nucleus Pm using proton-induced reactions and -ray spectroscopy to establish a new level scheme with 15 new levels, determine tentative spin-parity assignments and lifetimes, and interpret the results through large basis and projected shell model calculations, revealing a ground state, a nearby state, and a low-lying isomer.
