The strong coupling constants g(Sigma Q)Lambda(Q)pi (Q=b and c) are studied in the framework of the light cone QCD sum rules using the most general form of the baryonic currents. The predicted coupling constants are used to estimate the decay widths for the Sigma(Q)->Lambda(Q)pi decays which are compared with the predictions of the other approaches and existing experimental data.

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.
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...
Magnetic dipole moment of the light tensor mesons in light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (IOP Publishing, 2010-07-01)
The magnetic dipole moments of the light tensor mesons f(2), a(2) and the strange K-2*(0)(1430) tensor meson are calculated in the framework of the light cone QCD sum rules. It is observed that the values of the magnetic dipole moment for the charged tensor particles are considerably different from zero. These values are very close to zero for the light neutral f(2) and a(2) tensor mesons, while it has a small nonzero value for the neutral strange K-2*(0)(1430) tensor meson.
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.
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...
