Effects of a dense medium on parameters of doubly heavy baryons

Abstract

The spectroscopic properties of the doubly heavy spin-$1/2$ baryons ${\Xi }_{Q{Q}^{\prime }}$, ${\Xi }_{Q{Q}^{\prime }}^{\prime }$, ${\Omega }_{Q{Q}^{\prime }}$ and ${\Omega }_{Q{Q}^{\prime }}^{\prime }$, with heavy quarks $Q$ and $Q^{\prime }$ 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 $\rho \in [0,1.4]{\rho }_{sat}$, with ${\rho }_{sat}=0.11^{3}Ge{V}^3$ 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 ${\Xi }_{Q{Q}^{\prime }}$ and ${\Xi }_{Q{Q}^{\prime }}^{\prime }$ baryons with two heavy quarks and one $u$ or $d$ quark are affected by the medium, considerably. It is also seen that the ${\Omega }_{Q{Q}^{\prime }}$ and ${\Omega }_{Q{Q}^{\prime }}^{\prime }$ states, containing two heavy quarks and one $s$ quark do not see the dense medium, at all. The value of mass for the ${\Xi }_{cc}$ state obtained at $\rho \to 0$ 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.
