Abstract：
In this paper, the one-loop self energy of λφ³ theory is calculated by using Krein regularization in four and six dimensions and the result, which is finite, is compared with the conventional result of λφ³ theory in Hilbert space. The self energy is calculated in the one-loop approximation and the result is automatically regularized as a result of "Krein Regularization".
