Relations for low-energy constants in baryon chiral perturbation theory with explicit $\Delta (1232)$ derived from the chiral quark model

Jun Jiang, Shao-Zhou Jiang, Shi-Yuan Li +3

We study the relations between low-energy constants (LECs) in the chiral Lagrangians with $\Delta (1232)$ and those in the quark-level description model up to the third chiral order. Ten…
