At O(p^3) in heavy baryon chiral perturbation theory, sextet heavy baryons acquire polarizabilities from pion/kaon loops and from B6* to B6 magnetic transitions, while antitriplet heavy baryons have zero polarizability.

abstract
The transition form factors responsible for the radiative $\Sigma_Q \to \Lambda_Q \gamma$ and $\Xi_Q^\prime \to \Xi \gamma$ decays of the negative parity baryons are examined within light cone QCD sum rules. The decay widths of the radiative transitions are calculated using the obtained results of the form factors.

Electromagnetic polarizabilities of the spin-$\frac{1}{2}$ singly heavy baryons in heavy baryon chiral perturbation theory
At O(p^3) in heavy baryon chiral perturbation theory, sextet heavy baryons acquire polarizabilities from pion/kaon loops and from B6* to B6 magnetic transitions, while antitriplet heavy baryons have zero polarizability.
