The form factors of the bN+- decay are calculated in the framework of the light cone QCD sum rules. In the calculations the contribution of the negative parity b baryon is eliminated by constructing the sum rules for different Lorentz structures. Furthermore the branching ratio of the semileptonic bN+- decay is calculated. The numerical study for the branching ratio of the bN+- decay indicates that it is quite large and could be measurable at future planned experiments to be conducted at LHCb.

Radiative decays of the p-wave charmed heavy baryons
Alıyev, Tahmasıb; Savcı, Mustafa (Springer Science and Business Media LLC, 2019-05-23)
The radiative decays of the p-wave charmed heavy baryons to the ground state baryon states are studied in the framework of the light cone QCD sum rules method. Firstly, the transition form factors that describe these transitions are estimated and then, using these form factors, the corresponding decay widths are calculated. A comparison of our results for the decay widths with those predicted by the other approaches existing in the literature is performed.
phi -> KK decay in light cone QCD
Alıyev, Tahmasıb; Savcı, Mustafa (Springer Science and Business Media LLC, 2003-11-01)
The coupling constant of phi --> KK decay is calculated by light cone QCD sum rules. The result obtained for g(phiKK) = (4.9 +/- 0.8) is in good agreement with the existing experimental results.
Form factors of D-s(+) -> phi(l)over-bar nu decay in QCD light cone sum rule
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (Springer Science and Business Media LLC, 2004-12-01)
We calculate the form factors V, A(1), A(2) and A(0) appearing in the D-s --> phi transition by the light cone QCD sum rule method. We compare our results on these form factors with the current experimental results and existing theoretical calculations.
Radiative B-* meson decays in QCD sum rules
Alıyev, Tahmasıb; Pak, NK (Springer Science and Business Media LLC, 1997-01-01)
The decay constant g(B)* of the B* mesons and the transition amplitudes of the radiative decays B-a* --> B-a gamma are calculated in the frame-work of QCD sum rules. It is shown that the decay rates B* --> B gamma are one order smaller than the corresponding D* meson decays.
Nature of the Omega (2012) through its strong decays
Alıyev, Tahmasıb; SARAÇ OYMAK, YASEMİN; SUNDU PAMUK, HAYRİYE (Springer Science and Business Media LLC, 2018-11-03)
We extend our previous analysis on the mass of the recently discovered Omega (2012) state by investigation of its strong decays and calculation of its width employing the method of light cone QCD sum rule. Considering two possibilities for the quantum numbers of Omega (2012) state, namely 1P orbital excitation with J(P) = 3/2(-) and 2S radial excitation with J(P) = 3/2(+), we obtain the strong coupling constants defining the Omega (1P/2S) -> Xi K decays. The results of the coupling constants are then used t...
