A multimodal, uncertainty-quantified set of leading-power fragmentation functions for all-charm pentaquarks is constructed and applied to NLL/NLO+ pentaquark-plus-jet production at future hadron colliders.
Born-Oppenheimer approximation calculations for doubly heavy hadrons match Gaussian expansion benchmarks at small heavy quark masses but diverge at larger masses, with Slater-type functions overestimating and Gaussian-type underestimating binding energies.
Simulations reveal substantial differences in transverse momentum spectra between compact T_cc tetraquarks formed at partonic level and molecular X(3872) states formed at hadronic level, plus production asymmetry and source-characterizing coalescence parameters.
Radiative decays of hadronic molecules require careful treatment of scale hierarchies to resolve interpretive confusions, as demonstrated by reviewing decay types and instructive examples.

Assessing the validity of the Born-Oppenheimer approximation in potential models for doubly heavy hadrons
