Abstract

We construct the relativistic chiral Lagrangians with decuplet baryons up to the order O(p4)\mathcal{O}(p^4) (one loop). For the meson-decuplet-decuplet couplings, there are 1, 13, 55, and 548 terms in the O(p1)\mathcal{O}(p^1)-O(p4)\mathcal{O}(p^4) order Lagrangians, respectively. For the meson-octet-decuplet Lagrangians, the number of independent terms from O(p1)\mathcal{O}(p^1) to O(p4)\mathcal{O}(p^4) are 1, 5, 67, and 611, respectively. For convenience of applications, the πΔΔ\pi\Delta\Delta and πNΔ\pi N\Delta chiral Lagrangians are picked out. This new form of Δ\Delta Lagrangians is equivalent to the original isovector-isospinor one and we establish relations between these two forms.
