The light cone QCD sum rules method is used to calculate the transition form factor for the radiative phi --> f(0gamma) decay, assuming that the quark content of the f(0) meson is pare (s) over bars state. The branching ratio is estimated to be beta(phi --> f(0)gamma) = 3.5 x (1 +/- 0.3) x 10(-4). A comparison of our prediction on branching ratio with the theoretical results and experimental data existing in literature is presented.

Radiative Delta -> N gamma decay in light cone QCD
Alıyev, Tahmasıb; Savcı, Mustafa (1999-12-01)
The g(Delta N gamma) coupling for the Delta-->N gamma decay is calculated in the framework of the light cone QCD sum rules and is found to be g(Delta N gamma)=(1.6+/-0.2) GeV-1. Using this value of g(Delta N gamma) we estimate the branching ratio of the Delta(+)-->N gamma decay, which is in a very good agreement with the experimental result. [S0556-2821(99)02023-8].
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.
Tensor form factors of B -> K-1 transition from QCD light cone sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-05-30)
The tensor form factors of B into p-wave axial vector meson transition are calculated within light cone QCD sum rules method. The parametrizations of the tensor form factors based on the series expansion are presented.
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...
Vector meson dominance and radiative decays of heavy spin-3/2 baryons to heavy spin-1/2 baryons
Alıyev, Tahmasıb; Savcı, Mustafa (2012-04-10)
Using the calculated values of the strong coupling constants of the heavy sextet spin-3/2 baryons to sextet and antitriplet heavy spin-1/2 baryons with light vector mesons within the light cone QCD sum rules method, and vector meson dominance assumption, the radiative decay widths are calculated. These widths are compared with the "direct" radiative decay widths predicted in the framework of the light cone QCD sum rules.
