Tensor form factors of the octet hyperons in QCD

Light-cone QCD sum rules to leading order in QCD are used to investigate the tensor form factors of the $Σ-Σ$, $Ξ-Ξ$ and $Σ-Λ$ transitions in the range $1 GeV^2 \leq Q^2 \leq 10 GeV^2$. The DAs of $Σ$, $Ξ$ and $Λ$ baryon have been calculated without higher order terms. Then, study including higher order corrections have been done for $Σ$ and $Λ$ baryon. The result of form factors are obtained using these two DAs. We make a comparison with the predictions of the chiral quark soliton model.
