Physical Review D, 2021•APSThe chiral effective meson-baryon Lagrangian for the description of interactions between the
doubly charmed baryons and Goldstone bosons is constructed up to the order of q 4. The
numbers of linearly independent invariant monomials of O (q 2), O (q 3), and O (q 4) are 8,
32, and 218, in order. The obtained Lagrangian can be used to study the chiral dynamics
and relevant phenomenology of the doubly charmed baryons at complete one-loop level in
future. For completeness, the nonrelativistic reduction of the Lagrangian is also discussed.
