KünyeSUNDU, H., SÜNGÜ, J.Y., ŞAHİN, S., YİNELEK, N., AZİZİ, K. (2011). Strong coupling constants of bottom and charmed mesons with scalar, pseudoscalar, and axial vector kaons. Physical Review D, 83 (11), pp. 114009/1-114009/14. http://dx.doi.org/10.1103/PhysRevD.83.114009.
The strong coupling constants, gD(s)DK(0)*, gB(s)BK(0)*, gD(s)*DK, gB(s)*BK, gD(s)*DK1 and gB(s)*BK(1), where K(0)*, K and K(1) are scalar, pseudoscalar, and axial-vector kaon mesons, respectively, are calculated in the framework of three-point QCD sum rules. In particular, the correlation functions of the considered vertices when both B(D) and K(0)*(K)(K(1)) mesons are off shell are evaluated. In the case of K(1), which is either K(1)(1270) or K(1)(1400), the mixing between these two states are also taken into account. A comparison of the obtained result with the existing prediction on g(Ds)*(DK) as the only coupling constant among the considered vertices, previously calculated in the literature, is also made.
