Constraints from a large-N_c analysis on meson-baryon interactions at chiral order Q^3

30 Aug 2019 Heo Yonggoo Kobdaj C. Lutz M. F. M.

We consider the chiral Lagrangian for baryon fields with J^P =\frac{1}{2}^+ or J^P =\frac{3}{2}^+ quantum numbers as constructed from QCD with up, down and strange quarks. The specific class of counter terms that are of chiral order Q^3 and contribute to meson-baryon interactions at the two-body level is constructed... (read more)
