QCD sum rules identify three possible molecular dibaryons: Λ_c Σ_c with J^P=1^+ and anti-Λ_c Σ_c with J^P=0^- and 1^-; the other five channels are assigned as resonances.
QCD sum rules yield strong decay widths for Pc pentaquarks as molecular states that match experiment for known members and predict values for isospin cousins.
QCD sum rules applied to new color-bar3-bar3-bar3 currents give mass predictions for qssc anti-c pentaquarks with IJ^P = 1/2 1/2^-, 1/2 3/2^- and 1/2 5/2^-, indicating they are not scalar-diquark-scalar-diquark-antiquark states.
