Tensor form factors of the octet hyperons in QCD

Abstract

Light-cone QCD sum rules to leading order in QCD are used to investigate the tensor form factors of the $\Sigma -\Sigma$, $\Xi -\Xi$ and $\Sigma -\Lambda$ transitions in the range $1Ge{V}^2\le Q^2\le 10Ge{V}^2$. The DAs of $\Sigma$, $\Xi$ and $\Lambda$ baryon have been calculated without higher order terms. Then, study including higher order corrections have been done for $\Sigma$ and $\Lambda$ 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.
