- W2548652520 abstract "The question of whether there exist bound states of two heavy quarks $Q=(c,b)$ and antiquarks $bar Q = (bar c, bar b)$, distinct from a pair of quark-antiquark mesons, has been debated for more than forty years. 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 and bottom tetraquarks, respectively. Experimental search for these states in the relevant mass region is highly desirable." @default.
