NRQCD calculation finds ~1 MeV widths for T4c to gamma J/psi, tens of eV for T4b, and preferential c cbar annihilation in mixed bc states.
Fully heavy pentaquark fragmentation functions PQ5Q1.0 are completed for charm and bottom flavors and used to compute NLL/NLO+ semi-inclusive production rates at future colliders.
Reviews classes of exotic hadronic states in heavy-flavor systems as recurring experimental features across flavor sectors.
