On possible composite structure of scalar fields in expanding universe
Abstract Scalar fields in curved backgrounds are assumed to be composite objects. As an example realizing such a possibility we consider a model of the massless tensor field $$l_{\mu \nu }(x)$$ l μ ν ( x ) in a 4-dim. background $$g_{\mu \nu }(x)$$ g μ ν ( x ) with spontaneously broken Weyl and scal...
