abstract

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 $p$, $\Sigma^+$ and $\Xi^o$. 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 $p$, $\Sigma^+$, and $\Xi^o$ 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.

In the chiral quark-soliton model with 1/N_c corrections, the isoscalar tensor charge is 0.81, the isovector anomalous tensor magnetic moment is 1.97, and the isoscalar tensor quadrupole moment is 5.98, completing the flavor decomposition.
