The transition magnetic dipole and electric quadrupole moments of the radiative decays of the sextet heavy flavored spin 3/2 to the heavy spin 1/2 baryons are calculated within the light cone QCD sum rules approach. Using the obtained results, the decay rate for these transitions are also computed and compared with the existing predictions of the other approaches.

Electric quadrupole and magnetic octupole moments of the light decuplet baryons within light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (2009-11-02)
The electric quadrupole and magnetic octupole moments of the light decuplet baryons are calculated in the framework of the light cone QCD sum rules. The obtained non-vanishing values for the electric quadrupole and magnetic octupole moments of these baryons show nonspherical charge distribution. The sign of electric quadrupole moment is positive for Omega(-). Xi*(-), Sigma*(-) and negative for Sigma*(+), which correspond to the prolate and oblate charge distributions, respectively. A comparison of the obtai...
Radiative decays of negative parity heavy baryons in the framework of the light cone QCD sum rules
Agamaliev, A.K.; Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2017-2)
The transition form factors responsible for the radiative Sigma(Q) -> Lambda(Q)gamma and Xi(')(Q) -> Xi(Q)gamma So decays of the negative parity baryons are examined within light cone QCD sum rules. The decay widths of the radiative transitions are calculated using the obtained results of the form factors. A comparison of our predictions on decay widths with the corresponding widths of positive parity baryons is given.
Radiative Omega(Q)* -> Omega(Q)gamma and Xi(Q)* -> Xi(Q)'gamma transitions in light cone QCD
Alıyev, Tahmasıb; SUNDU PAMUK, HAYRİYE (2015-01-14)
We calculate the magnetic dipole and electric quadrupole moments associated with the radiative Omega(Q)* -> Omega(Q)gamma and Xi(Q)* -> Xi(Q)'gamma transitions with Q = b or c in the framework of light cone QCD sum rules. It is found that the corresponding quadrupole moments are negligibly small, while the magnetic dipole moments are considerably large. A comparison of the results of the considered multi-pole moments as well as corresponding decay widths with the predictions of the vector dominance model is...
Light-cone sum rules for radial excitation of decuplet to octet baryons electromagnetic transition form factors
Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2021-11-01)
In this paper magnetic dipole moment form factor, G(M)((2))(Q(2)), describing the radial excitation of decuplet baryons to octet baryons electromagnetic transitions as well as the ratios, RSM = - 1/4m(2)(2) root 4(m2)(Q)(2)(2) + (m(2)(2) - Q(2) - m(1)(2))2 G(C)((2))(Q(2))/ G(M)((2))(Q(2)) and R-EM = -G(E)((2))(Q(2)) G(M)((2))(Q(2)) are calculated in the framework of light-cone sum rules. We also estimate the degree of the violation of U-spin symmetry.
Diagonal and transition magnetic moments of negative parity heavy baryons in QCD sum rules
Alıyev, Tahmasıb; Barakat, T.; Savcı, Mustafa (2015-08-06)
Diagonal and transition magnetic moments of the negative parity, spin-1/2 heavy baryons are studied in the framework of the light cone QCD sum rules. By constructing the sum rules for different Lorentz structures, the unwanted contributions coming from negative-to-positive (positive-to-negative) parity transitions are removed. It is obtained that the magnetic moments of all baryons, except Lambda(0)(b), Sigma(+)(c), and Xi(c)'(+), are quite large. It is also found that the transition magnetic moments betwee...
