Scalar field radiation emitted by an accelerated scalar point source: A classical field theory approach

In this paper we will use classical field theory to address the interaction of an accelerated point source with a non-massive Klein-Gordon-Fock (KGF) field in Minkowski spacetime. For this, initially, we obtain the KGF equation for the non-massive scalar field via lagrangian formalism and the scalar potential through Green's function formalism. Finally, we reach the expression of the power radiated by a point scalar source under the influence of this field and its covariant generalization.
