| contents | We have studied the chiral-odd generalized parton distributions (GPDs) for the octet baryons within the framework of diquark spectator model, emphasizing the difference arising from different quark flavors of $p$, $Σ^+$ and $Ξ^o$. The quark-quark correlator for the tensor current has been solved to investigate the transversely polarized quark dynamics using light-cone wave functions. In the forward limit, transversity distributions of all the constituent quark flavors of $p$, $Σ^+$, and $Ξ^o$ have been studied. Additionally, the lowest moment of GPD $H_T$ and the combination of GPDs $E_T$ and $\tilde{H}_T$ have also been investigated. Our results are comparable with other available model predictions and lattice data for the case of $p$. Furthermore, we have presented a comparative analysis of tensor charges and anomalous tensor magnetic moments for all the constituent quark flavors of the considered baryons, comparing them with available data obtained from different approaches. |
