Within the Bethe-Salpeter framework the authors find bound-state solutions for D anti-D pairs under all three coupling sets examined and for Ds anti-Ds pairs only in a restricted region, yielding predicted B+ branching fractions of 1.09e-5 to 2.006e-3 and 1.56e-6 to 4.14e-4 respectively.

Comprehensive Mass Predictions: From Triply Heavy Baryons to Pentaquarks
Machine learning models trained on known hadron data and an extended Gürsey-Radicati mass formula predict masses for triply heavy baryons and numerous pentaquark states, agreeing with available data and forecasting unobserved states.
