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.
Develops uncertainty-aware fragmentation functions PQ5Q1.1 for all-charm pentaquarks using multimodal perturbative and nonperturbative modeling for collider predictions.
Radiative decays of hadronic molecules require careful treatment of scale hierarchies to resolve interpretive confusions, as demonstrated by reviewing decay types and instructive examples.
