Abstract
We derive a new regularization method for the calculation of the (massless) scalar self-force in curved spacetime. In this method, the scalar self-force is expressed in terms of the difference between two retarded scalar fields: the massless scalar field and an auxiliary massive scalar field. This field difference combined with a certain limiting process gives the expression for the scalar self-force. This expression provides a new self-force calculation method.
