This paper resolves the longstanding challenge of incorporating nuclear shell effects into orbital-free density functional theory by developing a non-local kinetic energy density functional that successfully reproduces shell behaviors consistent with exact Kohn-Sham solutions.
This paper presents an extension of the MadGraph5_aMC@NLO framework that enables automated leading-order calculations for S-wave quarkonium and leptonium production within NRQCD and NRQED formalisms, offering seamless integration with Beyond the Standard Model scenarios and highlighting the necessity of careful theoretical analysis beyond simple velocity-scaling rules.
This study employs ab initio many-body methods (IMSRG and CC) alongside RPA to calculate isoscalar monopole sum rules in finite nuclei, demonstrating strong agreement between approaches and deriving nuclear matter incompressibility values consistent with phenomenological ranges.
This study demonstrates that a prototype Electron-Ion Collider Zero-Degree Calorimeter, after being irradiated to simulate one year of full-luminosity operation, can be successfully calibrated on a channel-by-channel basis using cosmic-ray data, maintaining a sufficient signal-to-noise ratio despite significant and non-uniform radiation damage to its SiPMs.
This paper introduces an efficient and highly accurate method for representing nuclear densities using an orthogonal basis set derived from Principal Component Analysis of relativistic continuum Hartree-Bogoliubov calculations, which significantly outperforms traditional Fourier-Bessel and Sum-of-Gaussians approaches in convergence and precision.
The BECQUEREL experiment at JINR utilizes nuclear emulsion and automated microscopy to identify various unstable nuclear states, including the Hoyle state and Be, in the relativistic dissociation of nuclei, providing new insights into nuclear clustering and astrophysical fusion scenarios.
Using dijet-hadron correlations in lead-lead and proton-proton collisions at 5.02 TeV, the CMS collaboration firmly established the existence of a jet diffusion wake—a depletion of particles opposite to the jet direction—with a statistical significance exceeding 5 standard deviations, providing new insights into quark-gluon plasma properties.
This paper employs an Effective Field Theory framework to derive a factorization formula for inclusive jet production in dense media, demonstrating that both the Landau-Pomeranchuk-Migdal effect and color decoherence are governed by a single dimensionless parameter and can be systematically incorporated into jet quenching phenomenology through multi-sub-jet operators.
This paper proposes a novel experimental search for dark photons at electron accelerators using inverse Compton scattering () with laser photons and a 3 GeV electron beam, demonstrating that this setup can probe unexplored regions of dark sector parameter space through photon counting techniques.
A fixed-target program at the Electron-Ion Collider would significantly advance nuclear physics by providing high-statistics data to constrain cold nuclear matter effects, map the QCD phase diagram at low energies, and measure critical cross sections for space radiation protection.
