First NNLO QCD short-distance coefficients for the ³S₁⁽⁸⁾ gluon fragmentation function are obtained numerically to high precision, with analytic endpoint logarithms reconstructed for threshold resummation.
The OMG3Q1.1 framework delivers the first uncertainty-quantified set of fragmentation functions for all-heavy Ω_{3Q} baryons via diquark-inspired inputs, HF-NRevo evolution, and replica-based error estimation.
Proposes new photon line shape and branching fraction extraction method for J/psi to gamma eta_c, claiming compatibility between PDG data correlations and lattice QCD widths via profile scan.
NRQCD-based calculation extended via resolved pomeron model yields predictions for inclusive diffractive heavy quarkonium photoproduction at LHC, with resolved processes contributing up to 44% in pp collisions for Υ rapidity distributions.
Calculations of excitation functions, momentum spectra, and transparency ratios for χ_c1(1P) on 12C and 184W nuclei demonstrate sensitivity to different absorption cross-section scenarios, proposed for extraction via future CEBAF data.
