The (Sigma_Q-Lambda_Q) transition magnetic moments in light cone QCD sum rules

Using the general form of (Sigma_Q) and (Lambda_Q) (Q=b or c) currents, (Sigma_Q-Lambda_Q) transition magnetic moments are calculated in framework of the light cone QCD sum rules method. In this approach nonperturbative effects are described by the photon wave functions and only two-particle photon wave functions are taken into account. Our predictions on transition magnetic moments are (mu_{Sigma_c Lambda_c} = - (1.5 pm 0.4) mu_N) and (mu_{Sigma_b Lambda_b} = - (1.6 pm 0.4) mu_N). A comparison of our results with the ones existing in the literature is given.
