BOEFT quantifies threshold-induced shifts in quarkonium masses below threshold by solving coupled Schrödinger equations using lattice potentials and one parameter fixed to the χ_c1(3872) mass.
Bayesian MCMC sampling of Cornell and log-modified Cornell potentials reproduces known B_c states and supplies mass predictions for higher excitations with propagated uncertainties.
Direct gamma-gluon fusion dominates B_c photoproduction in ep collisions, with resolved gluon-gluon contributing O(10%) at low p_T across HERA to EIC energies.
Thermal QCD sum rules with updated inputs yield a suppression hierarchy Υ < J/ψ < B_c for masses and decay constants near Tc, calibrated to vacuum data and consistent with LHCb B_c splitting.
