Açıklama

The semileptonic decays of the open charm-bottom axial-vector tetraquark Z(s) = [cs][(b) over bar(s) over bar] to X(4274) (l) over bar nu(l) = e, mu, tau are explored by means of the QCD three-point sum rule method. Both Z(s) and X(4274) = [cs][(cs) over bar] are treated as color sextet diquark-antidiquark states. The full width of the decays Z(s) -> X(4274) (l) over bar nu(l) is found. Obtained predictions for Gamma(Z(s) -> X(4274)(l) over bar nu(l)) demonstrate that, as in the case of the conventional hadrons, the semileptonic transitions form a very small part of its full width.
