The 1S states of bb bbar cbar, cc cbar bbar, bb cbar cbar, and bc bbar cbar tetraquarks are predicted to have masses in 16.06-16.14, 9.65-9.74, 12.89-12.94, and 12.75-12.99 GeV with narrow fall-apart decay widths from tenths to several MeV.

QCD sum rules yield numerical tensor form factors for Ω^-, Σ^{*+}, and Ξ^{*-} up to 10 GeV² together with forward-limit quark tensor charges.
QCD sum rules yield masses 2.322 GeV (DK), 2.457 GeV (D*K), 2.538 GeV (DK*) matching D_s0(2317), D_s1(2460), D_s1(2536), with BK* at 6.158 GeV below threshold suggesting a bound state.
