Analysis of the radiative decays $\Sigma_Q \to \Lambda_Q \gamma$ and   $\Xi^\prime_Q \to \Xi_Q \gamma$ in light cone sum rules
  The light cone sum rules method is used in studying the radiative decays $\Sigma_Q \to \Lambda_Q \gamma$ and $\Xi^\prime_Q \to \Xi_Q \gamma$. Firstly, the sum rules for the form factor $F_2(Q^2=0)$ responsible for these transitions is constructed. Using this result the decay widths of the above--mentioned decays are calculated and analyzed. A comparison of our predictions on the decay widths of considered transitions with the predictions of the other approaches is presented.
