Tensor charges and form factors of SU(3) baryons in the self-consistent SU(3) chiral quark-soliton model

Abstract

We investigate the tensor form factors of the baryon octet within the framework of the chiral quark-soliton model, emphasizing those of the nucleon, taking linear $1/{N}_{c}$ rotational as well as linear ${m}_{s}$ corrections into account, and applying the symmetry-conserving quantization. We explicitly calculate the tensor form factors ${H}_{T}^{q}({Q}^{2})$ corresponding to the generalized parton distributions ${H}_{T}(x,\ensuremath{\xi},t)$. The tensor form factors are obtained for the momentum transfer up to ${Q}^{2}\ensuremath{\le}1\text{ }\text{ }{\mathrm{GeV}}^{2}$ and at a renormalization scale of $0.36\text{ }\text{ }{\mathrm{GeV}}^{2}$. We find for the tensor charges $\ensuremath{\delta}u=1.08$, $\ensuremath{\delta}d=\ensuremath{-}0.32$, and $\ensuremath{\delta}s=\ensuremath{-}0.01$ and discuss their physical consequences, comparing them with those from other models. Results for tensor charges for the baryon octet are also given.
