Description
The semileptonic decays of the open charm-bottom axial-vector tetraquark Zs = [cs][ anti b anti s] to X(4274) anti lνl, l = e, μ, τ are explored by means of the QCD three-point sum rule method. Both Zs and X(4274) = [cs][ anti c anti s] are treated as color sextet diquark-antidiquark states. The full width of the decays Zs → X(4274) anti lνl is found. Obtained predictions for Γ(Zs → X(4274) anti lνl) demonstrate that, as in the case of the conventional hadrons, the semileptonic transitions form a very small part of its full width. (orig.)
