A Solution of the Relativistic Schr\"odinger Equation for the δ-Function Potential in 1-dimensiona with Cutoff Regularization
Abstract
We study the solution of the relativistic Schr\"odinger equation for a point particle in 1-d under δ-function potential by using cutoff regularization. We show that the problem is renormalizable, and the results are exactly the same as the ones obtained using dimensional regularization.
