With the discovery of the doubly heavy $$\Xi _{cc}$$ Ξ cc baryon, comprehensive studies of the properties of the doubly heavy baryons are started. In the present work, we examine the $$\Xi _{bb} \rightarrow \Sigma _b \ell ^+ \ell ^-$$ Ξ bb → Σ b

The form factors of the $$\Lambda _{b} \rightarrow N^*\ell ^+ \ell ^-$$ decay are calculated in the framework of the light cone QCD sum rules. In the calculations the contribution of the negative parity $$\Lambda _b^*$$ baryon is eliminated by constr

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 (

By using the quark part of the energy-momentum tensor current, the gravitational formfactors of the $\ensuremath{\rho}$, $\ensuremath{\pi}$, and $K$ mesons are calculated within the light-cone sum rules method. In the considered version, the energy-m

We estimate the strong coupling constants of charmed and bottom mesons $ D_{(s)}^* $, $ D_{(s)1} $, $ B_{(s)}^* $, and $ B_{(s)1} $ with light vector mesons $ \rho $, $ \omega $, $ K^* $, and $ \phi $ within the framework of light-cone QCD sum rules.

Using the most general form of the interpolating current for baryons, the strong electric and magnetic coupling constants of light vector mesons $ \rho $ and $ K^* $ with doubly heavy baryons are computed within the light-cone sum rules. We consider

Using the QCD sum rules method, we estimate the mass and residues of the first radial excitations of octet baryons. The contributions coming from the ground state baryons are eliminated by constructing the linear combinations of the sum rules corresp

The strong coupling constants of negative parity heavy baryons belonging to sextet and antitriplet representations of SUf(3) with light π and K mesons are estimated within the light cone QCD sum rules. It is observed that each class of the sextet-se
