Dan Robu,Radu Curpen,Daniel Ilie,Titus Balanymmetry. This chapter develops the theory of nonlinear realizations of spacetime symmetries in close parallel with the previous discussion of internal symmetry. There are however some important differences. Notably, the spacetime coordinates and fields have to be treated together as independent vari

sons is used as a prototype of a relativistic effective field theory. The organization of the effective Lagrangian is explained in detail. The invariant Lagrangian is then worked out up to the next-to-leading order in the derivative expansion. The anomalous part of the effective Lagrangian is constr

George Kalmpourtzis,Margarida Romero,Cindy De Smet,Andreas Veglisn of effective actions for Nambu–Goldstone bosons. The first method is based on identification of various contributions to the effective Lagrangian with tensor fields on the coset space of broken symmetry. The requirement of invariance of the action is imposed and solved directly using the tools of
