In this paper, we analyze the vertices of doubly heavy spin-3/2-spin-1/2 baryons with light mesons within the method of light-cone QCD sum rules. These vertices are parametrized in terms of one (three) coupling constant(s) for the pseudoscalar (vector) mesons. The said coupling constants are calculated for all possible transitions. The results presented here can serve as useful information in experimental as well as theoretical studies of the properties of doubly heavy baryons.

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.
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.
Strong coupling constants of light pseudoscalar mesons with heavy baryons in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-01-31)
We calculate the strong coupling constants of light pseudoscalar mesons with heavy baryons within the light cone QCD sum rules method. It is shown that sextet-sextet, sextet-antitriplet and antitriplet-antitriplet transitions are described by one universal invariant function for each class. A comparison of our results on the coupling constants with the predictions existing in literature is also presented.
Strong coupling constants of decuplet baryons with vector mesons
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2010-11-10)
We provide a comprehensive study of strong coupling constants of decuplet baryons with light nonet vector mesons in the framework of light cone QCD sum rules. Using the symmetry arguments, we argue that all coupling constants entering the calculations can be expressed in terms of only one invariant function even if the SU(3)(f) symmetry breaking effects are taken into account. We estimate the order of SU(3)(f) symmetry violations, which are automatically considered by the employed approach.
Strong Coupling Constants of Negative Parity Heavy Baryons with pi and K Mesons
Alıyev, Tahmasıb; Bilmiş, Selçuk; Savcı, Mustafa (2017-01-01)
The strong coupling constants of negative parity heavy baryons belonging to sextet and antitriplet representations of SUf(3) with light pi and K mesons are estimated within the light cone QCD sum rules. It is observed that each class of the sextet-sextet, sextet-antitriplet, and antitriplet-antitriplet transitions can be described by only one corresponding function. The pollution arising from the positive to positive, positive to negative, and negative to positive parity baryons transitions is eliminated by...
