The electromagnetic decays of the charmed and bottom baryons in chiral perturbation theory

Understand

We have investigated the electromagnetic decays of the antitriplet and sextet charmed baryon systems with $J^P= \frac{1}{2}^+, \frac{3}{2}^+$ in the framework of the heavy baryon chiral perturbation theory.

• We first construct the chiral Lagrangians at $O(p^2)$ and $O(p^3)$.
• Then we calculate the electromagnetic (EM) decay amplitudes of the charmed baryon systems up to $O(p^3)$.
• With the help of the quark model, we estimate the low energy constants.
