All transitions among the heavy spin-3/2 sextet baryons with participation of the light vector mesons (B(Q)(not equal)B(Q)V) are investigated in the framework of the light cone sum rules. These vertices are described by four coupling constants. The corresponding sum rules are derived for each coupling constant. It is shown that the correlation functions of different transitions can be described by only one invariant function.

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.
Analysis of heavy spin-3/2 baryon-heavy spin-1/2 baryon-light vector meson vertices in QCD Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2011-05-16) The heavy spin-3/2 baryon-heavy spin-1/2 baryon vertices with light vector mesons are studied within the light cone QCD sum rules method. These vertices are parametrized in terms of three coupling constants. These couplings are calculated for all possible transitions. It is shown that correlation functions for these transitions are described by only one invariant function for every Lorenz structure. The obtained relations between the correlation functions of the different transitions are structure independe...
Strong BQQ′∗BQQ′V vertices and the radiative decays of BQQ∗→BQQγ in the light-cone sum rules Alıyev, Tahmasıb; Şimşek, K. (2021-05-01) The strong coupling constants of spin-3/2 to spin-1/2 doubly heavy baryon transitions with light vector mesons are estimated within the light-cone QCD sum rules method. Moreover, using the vector-meson dominance ansätz, the widths of radiative decays BQQ∗→BQQγ are calculated. The results for the said decay widths are compared to the predictions of other approaches.
kappa K+pi(-) vertex in light cone QCD sum rules Baytemir, G.; SARAÇ OYMAK, YASEMİN; Yılmaz, Osman (American Physical Society (APS), 2010-05-01) In this work we study the kappa K+pi(-) vertex in the framework of light cone QCD sum rules. We predict the coupling constant g kappa K+pi(-) to be g kappa K+pi(-) = (6.0 +/- 1.0) GeV and estimate the scalar f(0) - sigma mixing angle from the experimental ratio g(2)(kappa -> K pi)/g(2)(sigma -> pi pi).
Isovector axial vector and pseudoscalar transition form factors of Delta in QCD KÜÇÜKARSLAN, AYŞE; Ozdem, U.; Özpineci, Altuğ (2014-09-03) We investigate the isovector axial vector and pseudoscalar form factors of Delta baryon by employing light-cone QCD sum rules. Numerical calculations show that the form factors can be well fitted by the exponential form. We make a comparison with the predictions of lattice QCD, chiral perturbation theory and quark model.
