Light $\mathrm{\Xi }$ hypernuclei in four-body cluster models

Detailed structure calculations in ${}_{{\mathrm{\Xi }}^{-}}^{12}$Be, ${}_{{\mathrm{\Xi }}^{-}}^5$H, ${}_{{\mathrm{\Xi }}^{-}}^9$Li, ${}_{{\mathrm{\Xi }}^{-}}^7$H and ${}_{{\mathrm{\Xi }}^{-}}^{10}$Li are performed within the framework of the microscopic two-, three- and four-body cluster models using the Gaussian Expansion Method.
