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.
Sigma(Q)Lambda(Q) transition magnetic moments in light cone QCD sum rules
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2002-05-01)
Using the general form of Sigma(Q) and Lambda(Q) (Q=b or c) currents, Sigma(Q)Lambda(Q) transition magnetic moments are calculated in the framework of the light cone QCD sum rules method. In this approach nonperturbative effects are described by the photon wave functions and only two-particle photon wave functions are taken into account. Our predictions of the transition magnetic moments are mu(Sigmac)Lambda(c)=-(1.5+/-0.4)mu(N) and mu(Sigmab)Lambda(b)=-(1.6+/-0.4)mu(N). A comparison of our results with the...
Strong coupling constants of the octet baryons to Kand pi mesons in light cone QCD sum rules
Alıyev, Tahmasıb; Özpineci, Altuğ (2007-06-20)
In this work, the strong coupling constants of the octet baryons to the K and pi mesons are studied within the Light Cone QCD sum rule method. It is well known that in the SU(3)(f) limit, these couplings can be expressed in terms of only 2 constants, so called F and D constants. In this work, the SU(3)(f) symmetry violating effects are also studied and it is shown that all the coupling constants can be expressed in terms of four analytical functions of the quark parameters.
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...
Strong Coupling Constants of Heavy Baryons With Light Mesons in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (2012-06-21)
The strong coupling constants of the heavy spin-1/2 and spin-3/2 baryons with light pseudoscalar and vector mesons are calculated in the framework of the light cone QCD sum rules. Using the symmetry arguments, some structure independent relations among different correlation functions are obtained. It is shown that all possible transitions are described by only one invariant function, whose explicit expression is structure dependent.
