The strong coupling constant g kappa (0)*kappa pi of the scalar K-0* meson decay to K pi is calculated in light cone QCD sum rule. The predicted value of the coupling constant g kappa (0)*kappa pi is in a good agreement with the experimental result.

The Sigma(0)Lambda transition magnetic moment in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2001-09-20) Using the general form of the Sigma (0) and Lambda currents, the Sigma (0)Lambda transition magnetic moment is calculated in framework of the light cone QCD sum rules. A comparison of our result on this quantity with the existing theoretical results and experimental data is presented.
THE G(B)ASTERISK(B-PI) COUPLING-CONSTANT IN QCD SUM-RULES Alıyev, Tahmasıb; ILTAN, E; PAK, NK (1995-05-25) The decay constant for the strong off-shell B* --> B pi decay in the context of QCD sum rules is calculated.
Strong coupling constants of the octet baryons to Kand pi mesons in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ (2007-06-20) In this work, the strong coupling constants of the octet baryons to the K and pi mesons are studied within the Light Cone QCD sum rule method. It is well known that in the SU(3)(f) limit, these couplings can be expressed in terms of only 2 constants, so called F and D constants. In this work, the SU(3)(f) symmetry violating effects are also studied and it is shown that all the coupling constants can be expressed in terms of four analytical functions of the quark parameters.
The strong coupling constants of excited positive parity heavy mesons in light-cone QCD

Alıyev, Tahmasıb; Savcı, Mustafa (1997-01-02)

We calculate the strong coupling constants g(p**p*pi), where P** (D**, B**) is the 1(+) p-wave state, in the framework of the light-cone QCD sum rules, and using these values of g(p**p*pi), we compute the hadronic decay widths for D** --> D*pi and B** --> B*pi.
Strong coupling constant of negative parity octet baryons with light pseudoscalar mesons in light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2017-01-01) The strong coupling constants of the pi and K mesons with negative parity octet baryons are estimated within the light cone QCD sum rules. It is observed that all strong coupling constants, similarly to the case for the positive parity baryons, can be described in terms of three invariant functions, where two of them correspond to the well known F and D couplings in the SU (3)(f) symmetry, and the third function describes the SU(3)(f) symmetry violating effects. We compare our predictions on the strong coup...
