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.
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...
Strong coupling constants of decuplet baryons with vector mesons Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2010-11-10) We provide a comprehensive study of strong coupling constants of decuplet baryons with light nonet vector mesons in the framework of light cone QCD sum rules. Using the symmetry arguments, we argue that all coupling constants entering the calculations can be expressed in terms of only one invariant function even if the SU(3)(f) symmetry breaking effects are taken into account. We estimate the order of SU(3)(f) symmetry violations, which are automatically considered by the employed approach.
Spontaneous symmetry breaking at two loop in 3-d massless scalar electrodynamics Tan, PN; Tekin, Bayram; Hosotani, Y (Elsevier BV, 1996-11-21) In three-dimensional Maxwell-Chem-Simons massless scalar electrodynamics with phi(6) coupling, the U(1) symmetry is spontaneously broken at two loop order regardless of the presence or absence of the Maxwell term. Dimensional transmutation takes place in pure Chem-Simons scalar electrodynamics. The beta function for the phi(6) coupling is independent of gauge couplings.
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.
