Meson-Baryon Effective Chiral Lagrangian at $O(q^3)$ Revisited

After our work [1] was published, Frink and Meissner [2] pointed out that the O(q^3) three-flavour meson-baryon chiral Lagrangian presented there was not minimal. Here, we critically review their paper and revise ours. Remarkably, we find that the effective meson-baryon chiral Lagrangian at O(q^3) c...

Sumario:After our work [1] was published, Frink and Meissner [2] pointed out that the O(q^3) three-flavour meson-baryon chiral Lagrangian presented there was not minimal. Here, we critically review their paper and revise ours. Remarkably, we find that the effective meson-baryon chiral Lagrangian at O(q^3) contains 76 monomials, i.e. eight less than in [1] and two less than in [2].
