New relations between QCD Borel sum rules for strong coupling constants of K-mesons to baryons are derived. It is shown that starting from the sum rule for the coupling constants g(pi Sigma Sigma) and g(pi Sigma Lambda) it is straightforward to obtain corresponding sum rules for the g(KYN), G(KY Xi) couplings, Y = Sigma,Lambda.

QCD coupling constants and VDM
ERKOL, GÜRAY; Özpineci, Altuğ; Zamiralov, V. S. (2012-06-21)
QCD sum rules for coupling constants of vector mesons with baryons are constructed. The corresponding QCD sum rules for electric charges and magnetic moments are also derived and with the use of vector-meson-dominance model related to the coupling constants. The vector-dominance model (VDM) role as the criterium of reciprocal validity of the sum rules is considered.
Heavy chi(Q) (2) tensor mesons in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2010-06-14)
The masses and decay constants of the ground state heavy chi(Q2) (Q = b, c) tensor mesons are calculated in the framework of the QCD sum rules approach. The obtained results on the masses are in good consistency with the experimental values. Our predictions on the decay constants can be verified in the future experiments.
Baryon-Baryon-Meson Coupling Constants in QCD
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2010-06-23)
The strong coupling constant of decuplet and octet baryons to vector and pseudoscalar mesons are calculated in light cone QCD sum rules in general case and when the SU(3)(f) symmetry is taken into account. A comparison of the obtained results with the existing experimental data and predictions of the other nonperturbative approaches is also made.
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.
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.
