Using the light cone QCD Sum Rules Method, we study the rare B --> <nu(nu)over bar>gamma decay and find that the branching ratios are, B(B-s --> <nu(nu)over bar>gamma) similar or equal to 7.5 x 10(-8) , B(B-d --> <nu(nu)over bar>gamma) similar or equal to 4.2 x 10(-9). A comparison of our results on branching ratio with constituent quark and pole dominance model predictions are presented.

The gK(0)(*)K pi coupling constant in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (2001-01-01)
The strong coupling constant g kappa (0)*kappa pi of the scalar K-0* meson decay to K pi is calculated in light cone QCD sum rule. The predicted value of the coupling constant g kappa (0)*kappa pi is in a good agreement with the experimental result.
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...
gamma*N -> N* (1520) transition form factors in light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (2014-11-25)
The gamma*N -> N* (1520) reaction is studied in the framework of the light cone QCD sum rules method. The sum rules for the multipole form factors, namely, for the magnetic dipole G(M)(Q(2)), electric quadrupole G(E)(Q(2)), and Coulomb quadrupole G(C)(Q(2)) [i.e., form factors responsible for the gamma*N -> N* (1520) transition] are derived. Using these sum rules, the helicity amplitudes are presented as combinations of these multipole form factors, and their Q(2) dependences are studied. We compare our res...
THE G(B)ASTERISK(B-PI) COUPLING-CONSTANT IN QCD SUM-RULES
Alıyev, Tahmasıb; ILTAN, E; PAK, NK (1995-05-25)
The decay constant for the strong off-shell B* --> B pi decay in the context of QCD sum rules is calculated.
The Sigma(0)Lambda transition magnetic moment in light cone QCD sum rules
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2001-09-20)
Using the general form of the Sigma (0) and Lambda currents, the Sigma (0)Lambda transition magnetic moment is calculated in framework of the light cone QCD sum rules. A comparison of our result on this quantity with the existing theoretical results and experimental data is presented.
