BESIII reports 4.4σ evidence for transverse Ξ⁰ polarization in ψ(3686)→Ξ⁰Ξ⁰-bar together with improved measurements of branching fraction, decay amplitudes, and CP observables consistent with no violation.
A quark-diquark formalism extracts effective masses and couplings from known heavy baryon data to predict spectra across singly, doubly, and triply heavy sectors with two scenarios and a mass-dependent binding term.
Pion unpolarized quark GPDs at zero skewness are extracted from a data-driven fit to the electromagnetic form factor and PDFs using a parameterized form factor embedded in a PDF-plus-profile GPD framework.
Analysis of galaxy cluster and supernova data reveals a ~2σ directional variation in the Hubble constant, robust across calibration methods and aligned with the CMB dipole.
Chiral effective field theory and resonance chiral theory yield cross sections for e+e- to four pions that are one to two orders smaller than data, with hadronic vacuum polarization contributions to (g-2)μ of (0.680±0.062)×10^{-16} and (0.597±0.058)×10^{-16} for the two charge modes.
Models initial-state energy loss, nuclear shadowing, and final-state absorption on J/ψ and ψ(2S) production in p+A collisions, compares to SPS/Fermilab/HERA-B data, and extrapolates absorption levels for NA60+ and CBM.
