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