Description
Starting from the relativistic manner, in this work, we construct the non-derivative four-point interactions for Octet and Decuplet baryons in the Chiral Effective Field Theory (ChEFT). The non-relativistic expansion of the baryon fields has been considered up to the Next-Leading Order (NLO) of the three-momentum. Using the 1/$N_c$ operator product expansion up to 1/$N_c^2$, we can reduce the free parameters (coupling constants) of the ChEFT from 28 down to 13. Moreover, we will discuss the implications of the large-Nc scalings in ΩΩ and ΩN scatterings from the Lattice QCD data.
