The strong coupling constants of hadronic multiplets are fundamental parameters which carry information about the strong interactions among participating particles. These parameters can help us construct the hadron-hadron strong potential and gain information about the structure of the involved hadrons. Motivated by the recent observation of the doubly charmed state by LHCb, we determine the strong coupling constants among the doubly heavy spin-1/2 baryons, , and light pseudoscalar mesons, , K, and within the framework of the light cone QCD sum rules. The obtained results may help experimental groups in analysis of the related data at hadron colliders.

The strong coupling constants among hadronic multiplets, as fundamental parameters, carry information on the nature of strong interaction among the participating particles. These parameters can help us construct the hadron-hadron strong potential and gain information about the structure of the involved hadrons. Motivated by the recent observation of the doubly charmed Ξ cc state by LHCb, we determine the strong coupling constants among the doubly heavy spin-1/2 baryons, ΞQQ ′ and light pseudoscalar mesons, π, K, η and η ′ within the framework of the light cone QCD sum rules. The obtained results may help experimental groups in analyses of the related data at hadron colliders.

“…We hope that, by the development of experimental facilities, we will be able to detect other members of the doubly heavy baryons. The production mechanism of doubly heavy baryons has an important place in the literature [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. Naturally, a doubly heavy baryon can be produced using a two-step procedure: i-) in a hard interaction, a double heavy diquark is produced pertur-batively, ii-) and then it is transformed to the baryon within the soft hadronization process [34].…”

The spectroscopic properties of the doubly heavy spin-1/2 baryons Ξ QQ ′ , Ξ ′ QQ ′ , Ω QQ ′ and Ω ′ QQ ′ , with heavy quarks Q and Q ′ being b or/and c, are investigated in cold nuclear matter. In particular, the behavior of the mass of these particles with respect to the density of the medium in the range ρ ∈ [0, 1.4] ρsat, with ρsat = 0.11 3 GeV 3 being the saturation density of nuclear matter, is investigated. From the shifts in the mass and vector self energy of the states under consideration, it is obtained that Ξ QQ ′ and Ξ ′ QQ ′ baryons with two heavy quarks and one u or d quark are affected by the medium, considerably. It is also seen that the Ω QQ ′ and Ω ′ QQ ′ states, containing two heavy quarks and one s quark do not see the dense medium, at all. The value of mass for the Ξcc state obtained at ρ → 0 limit is nicely consistent with the experimental data. Our results on parameters of other members can be useful in the search for these states. The obtained results may also shed light on the future in-medium experiments aiming to search for the behavior of the doubly heavy baryons under extreme conditions.
