Combined heavy-quark symmetry and large-$N_c$ operator analysis for 2-body counterterms in the chiral Lagrangian with $D$ mesons and charmed baryons

Daris Samart, Chakrit Nualchimplee, Yupeng Yan

We construct, in the work, chiral $SU(3)$ Lagrangian with $D$ mesons of spin $J^P=0^{-}$ and $J^P=1^{-}$ and charmed baryons of spin $J^P=1/2^{+}$ and $J^P=3/2^{+}$. There are 42 leading t…
