Real scalar spin-0 field in five dimensions

M. F. Umar

Abstract

We generalized the Kaluza-Klein theory of massive real scalar spin-0 field in five dimensions with self-interaction term _4 . Fifth coordinate undergoes compactification and periodical. In potential term, we derived the self-interaction of different modes of field with strength 2_ and the complete Lagrangian. We determined the mass of field related to their modes. We also discussed the dimensional reduction D = 5 _ D = 4 of real scalar field, where in four dimensional spacetime we just observed the five dimensional zero mode of real scalar field. Keywords Kaluza-Klein theory, real scalar spin-0 field, five dimensions
