THE INVERSE HIGGS PHENOMENON IN NONLINEAR REALIZATIONS

摘要

Throughout the above consideration we concentrated on those aspects of the inverse Higgs phenomenon in which it differed from the direct one. It should be pointed out, however, that there exists one analogy between these phenomena. Both of them lead to a reduction of initial symmetry to lower one. In all the cases, the only trace of higher symmetry is relations between minimal and nonminimal coupling constants of true gauge and true Goldstone fields of a type of sum rules (Ⅱ.16), (III.17). Analogously, after eliminating the Goldstone fields from some Lagrangian by the usual Higgs phenomenon the only manifest invariance which remains is the invariance under a subgroup of stability of the vacuum. In the "unitary gauge" the whole symmetry one begins with manifests " itself through relations between parameters 01 Lagran-gians (i.e., masses, coupling constants).
