This paper reports on the successful conversion of the Manitoba II mass spectrometer into a versatile, steerable low-energy proton beam facility (25–35 keV) capable of characterizing silicon detectors for BSM searches like the Nab experiment by delivering a monoenergetic pencil beam with a 0.6–1.26 mm spot size over a 117 mm area.
This paper presents the first measurement of angular correlations between high-energy pions and slow protons in electron-nucleus scattering using the CLAS detector, revealing nuclear-mass-dependent trends that generally align with current theoretical models while highlighting specific discrepancies that guide future improvements in understanding cold-nuclear matter effects.
This paper presents an updated version of the TGlauberMC Monte Carlo code (v3.3) with improved nuclear density profiles and nucleon substructure treatments to provide precise predictions for initial-state observables and centrality-dependent multiplicity in upcoming oxygen-oxygen, neon-neon, and proton-oxygen collisions at the LHC.
This paper derives model-independent expansions to quantify leading corrections to the smoothness and on-shell approximations in femtoscopy and coalescence, demonstrating that while these corrections are generally small (at or below the percent level) for LHC energy collisions, they can be efficiently evaluated with the same numerical complexity as standard methods.
This closeout report for LDRD 23-050 details the physics case and conceptual design for a second, complementary Electron-Ion Collider (EIC) detector, outlining its scientific potential, innovative technology requirements, and strategic role in maximizing the EIC's multi-decade research capabilities.
This paper numerically investigates the time evolution of sound modes in a Bjorken-expanding Super-Yang-Mills plasma, revealing how longitudinal expansion-induced anisotropy splits the speed of sound into two distinct values and constructing an anisotropic hydrodynamic framework to interpret these findings for heavy-ion collision data.
This paper demonstrates that the Short-Baseline Near Detector (SBND) can probe previously unexplored light dark matter parameter spaces by detecting MeV-scale photon "blips" from nuclear de-excitation, utilizing state-of-the-art ab initio nuclear theory to predict signals from argon excited states up to 18 MeV.
This study utilizes PYTHIA8 to analyze charge balance functions of identified hadrons in high-multiplicity jets at TeV, revealing a narrowing balancing width and species-dependent dynamics that suggest multiparton interactions and color reconnection can generate collective-like features within small systems.
This paper presents a data-driven framework utilizing a Bidirectional Long Short-Term Memory (BiLSTM) neural network with multi-head attention to predict and optimize the yield of detector-grade high-purity germanium crystals by identifying key growth parameters such as impurity concentration and growth rate.
The RDK II collaboration reports the observation of thermal photons from accelerated electrons via radiative beta decay, confirming a one-dimensional Planck spectrum consistent with the dynamical Casimir effect and the moving mirror model.
