Spatial integrals in non-standard dimensions via Gaussian measure and analytic continuation
Juuso Österman
Non-integer dimensions are commonplace in quantum field theories (QFTs) through dimensional regularization. In particular this affects angular calculations involving dot products.…

On Finite Representation of Dimensionally Regularized One-loop Integrals
Juuso Österman
Dimensional regularization of Euclidean momentum space integrals is a highly successful technique in renormalization of quantum field theories. While it yields a straightforward al…
