B\(_1\)B\(_{s0}\)K and B\(_1\)B\(_{s1}\)K strong couplings in three-point QCD sum rules

An improved calculation of the strong coupling constants of B\(_1\)B\(_{s0}\)K and B\(_1\)B\(_{s1}\)K vertices is presented in the framework of the three-point QCD sum rules. The coupling constants are calculated, when both the B\(_{s0}\)(B\(_{s1}\)) and K states are off-shell. Considering the \(SU_...

Zusammenfassung:An improved calculation of the strong coupling constants of B\(_1\)B\(_{s0}\)K and B\(_1\)B\(_{s1}\)K vertices is presented in the framework of the three-point QCD sum rules. The coupling constants are calculated, when both the B\(_{s0}\)(B\(_{s1}\)) and K states are off-shell. Considering the \(SU_f(3)\) symmetry, the results are compared with the existing predictions.
