Analysis of $γ^\ast Λ\to Σ^0$ transition in QCD    [PDF]

T. M. Aliev, K. Azizi, M. Savci

The $\gamma^\ast \Lambda \to \Sigma^0$ transition form factors are investigated within the light--cone QCD sum rules method. Using the most general form of the interpolating current of $\Sigma^0$ baryon and the distribution amplitudes of $\Lambda$ baryon we calculate the $Q^2$ dependence of the electromagnetic form factors. Our result are compared with the predictions of the covariant spectator quark model.
