摘要：

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 1 GeV2 <= Q(2) <= 10 GeV2. The DAs of Sigma,Xi, and. baryon have been calculated without higher-order terms. Then, studies including higher-order corrections have been done for the Sigma and. baryon Lambda The resulting form factors are obtained using these two DAs. We make a comparison with the predictions of the chiral quark soliton model.
