Strong interaction of doubly heavy spin-3/2 baryons with light vector mesons

Abstract We calculate the strong coupling constants among the doubly heavy spin- $$ \frac{3}{2} $$ 3 2 baryons $$\Xi ^*_{QQ}$$ Ξ QQ ∗ and $$\Omega ^*_{QQ}$$ Ω QQ ∗ , with Q and $$ Q' $$ Q ′ being c or b quark, with light vector meson by means of the light-cone QCD sum rules. The matrix elements...

description Abstract We calculate the strong coupling constants among the doubly heavy spin- $$ \frac{3}{2} $$ 3 2 baryons $$\Xi ^*_{QQ}$$ Ξ QQ ∗ and $$\Omega ^*_{QQ}$$ Ω QQ ∗ , with Q and $$ Q' $$ Q ′ being c or b quark, with light vector meson by means of the light-cone QCD sum rules. The matrix elements defining these vertices are described by four coupling constants $$ g_1$$ g 1 , $$ g_2$$ g 2 , $$ g_3$$ g 3 , and $$ g_4 $$ g 4 . The unwanted pollution coming from the doubly heavy spin- $$ \frac{1}{2} $$ 1 2 baryons are removed by a special ordering of Dirac matrices and selection of appropriate Lorentz structures. The strong coupling constants are basic parameters that carry information on the nature of the strong interaction among hadronic multiplets. Investigation of these parameters may help physicists in the construction of the strong potentials among the doubly heavy baryons and light vector mesons. The values obtained for the strong coupling constants may also help experimental groups in analyses of the data produced at various hadron colliders.
