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.
Resummed quarkonium fragmentation functions are derived to all orders in perturbation theory, resolving threshold singularities without nonperturbative model functions.
An auxiliary-field effective theory yields a lineshape parametrization for molecular X(3872) that consistently describes deuteron scattering data and differs from the Flatté form used for compact interpretations.
The 0+ T_bc tetraquark is predicted near the B D-bar threshold while the 1+ state appears as an S-wave resonance 23-28 MeV above the B* D-bar threshold, with masses 7.143-7.222 GeV.
Leading-order predictions for three-body point production rates of B and B* meson systems are derived in short-range NREFT from two-body input alone.
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.
