We suggest some means of producing and observing $Q_1 Q_2 \\bar Q_3 \\bar Q_4$ resonant states, concentrating on the $c c \\bar c \\bar c$ channel which is most easily produced and the $b b \\bar b \\bar b$ channel which has a better chance of being relatively narrow. We obtain $M_{(cc)(\\bar c \\bar c)} = 6,192 \\pm 25$ MeV and $M_{(bb)(\\bar b \\bar b)} = 18,826 \\pm 25$ MeV, for the charmed ","authors_text":"Jonathan L.
