The coupling constants of K and pi mesons with the octet baryons are studied in light cone QCD sum rules taking into account SU(3)(f) flavor symmetry breaking effects, but keeping the SU(2) isospin symmetry intact. It is shown that, in the SU(3)(f) flavor symmetry breaking case, all of the couplings can be written in terms of four universal functions instead of F and D couplings which exist in the SU(3)(f) symmetry case. A comparison of our results of kaon and pion-baryon couplings with existing theoretical and experimental results in the literature is performed.

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...
Vector meson-baryon strong coupling constants in light cone QCD sum rules
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (American Physical Society (APS), 2009-07-01)
Using the most general form of the interpolating current of the baryons, the strong coupling constants of the light vector mesons with the octet baryons are calculated within the light cone QCD sum rules. The SU(3)(f) symmetry breaking effects are taken into account in the calculations. It is shown that each of the electric and magnetic coupling constants can be described in terms of three universal functions. A detailed comparison of the results of this work on aforementioned couplings with the existing th...
Strong transitions of decuplet to octet baryons and pseudoscalar mesons
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2010-12-01)
The strong coupling constants of light pseudoscalar pi, K and eta mesons with decuplet-oclet baryons are studied within light cone QCD sum rules, where SU(3)(f) symmetry breaking effects are taken into account It is shown that all coupling constants under the consideration are described by only one universal function even if SU(3)(f) symmetry breaking effects are considered.

Strong coupling constants of light pseudoscalar mesons with heavy baryons in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-01-31)
We calculate the strong coupling constants of light pseudoscalar mesons with heavy baryons within the light cone QCD sum rules method. It is shown that sextet-sextet, sextet-antitriplet and antitriplet-antitriplet transitions are described by one universal invariant function for each class. A comparison of our results on the coupling constants with the predictions existing in literature is also presented.
Heavy baryon-light vector meson couplings in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-02-15)
The strong coupling constants of heavy baryons with light vector mesons are calculated in the framework of the light cone QCD sum rules using the most general form of the interpolating currents for the heavy baryons. It is shown that the sextet sextet, sextet-antitriplet and antitriplet-antitriplet transitions are described by one invariant function for each class of transitions. The values of the electric and magnetic coupling constants for these transitions are obtained.
