Abstract

The gamma(*) Lambda -> 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 baryon we calculate the Q(2) dependence of the electromagnetic form factors. Our results are compared with the predictions of the covariant spectator quark model.
