Abstract

We investigate the behavior of the doubly heavy spin-3/2 baryons in cold nuclear matter. In particular, we study the variations of the spectroscopic parameters of the ground state ΞQQ* and ΩQQ* particles, with Q and Q being b or c quark, with respect to the changes in the density of the nuclear medium. We find the shifts on the parameters under question at saturation medium density compared to their vacuum values. It is observed that the parameters of the ΞQQ* states containing two heavy quarks and one up or down quark are affected by the medium, considerably. The parameters of the ΩQQ* states containing two heavy quarks and one strange quark, however, do not show any sensitivity to the density of the cold nuclear medium. We also discuss the variations of the vector self-energy at each channel with respect to the changes in the density. The negative shifts in the mass of ΞQQ* states due to nucleons in the medium can be used to study the doubly heavy baryons’ interactions with the nucleons. The results obtained can also be used in analyses of the results of the future in-medium experiments.
