Abstract
In the study of $\mathrm{CP}$ violation signals in $\stackrel{\ensuremath{\rightarrow}}{\ensuremath{\Omega}}\ensuremath{\pi}\ensuremath{\Xi}$ nonleptonic decays, the strong $J=3/2$ P, and D phase shifts for the $\ensuremath{\pi}\ensuremath{\Xi}$ final-state interactions are needed. These phases are calculated using an effective Lagrangian model that considers $\ensuremath{\Xi},$ ${\ensuremath{\Xi}}^{*}(1530),$ $\ensuremath{\rho},$ and the $\ensuremath{\sigma}$ term, in the intermediate states. The $\ensuremath{\sigma}$ term is calculated in terms of the scalar form factor of the baryon.
