Abstract
We construct the Lorentz-invariant chiral Lagrangians up to the order by including as an explicit degree of freedom. A full one-loop investigation on processes involving can be performed with them. For the Lagrangian, one obtains 38 independent terms at the order and 318 independent terms at the order . For the Lagrangian, we get 33 independent terms at the order and 218 independent terms at the order . The heavy baryon projection is also briefly discussed.
