Fermions in 5D brane world models

Abstract

Abstract. In the present manuscript the fermion fields in the background of 5D brane world models with compact extra dimension are examined. It is shown that the only case that allows one to perform the Kaluza-Klein decomposition in a mathematically consistent way without unnatural fine-tunings and possible pathologies, is the one which does not admit localization of the zero mode. The report is based on the results presented in [1].

Particle creation by a massless spin-1/2 field in a warped cosmological braneworld scenario

“…Proceeding further, an analysis of a quantised spin 1/2 field and the corresponding REMT in the context of warped cosmological thick braneworld with a dynamic extra dimension is our objective here. Few studies on fermionic fields in higher dimensions including warped braneworld background has been reported in the literature [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]. However, in case of warped braneworld models, the background geometries were assumed to be static.…”
