To $d$, or not to $d$: Recent developments and comparisons of regularization schemes
arXiv:1705.01827 · doi:10.1140/epjc/s10052-017-5023-2
Abstract
We give an introduction to several regularization schemes that deal with ultraviolet and infrared singularities appearing in higher-order computations in quantum field theories. Comparing the computation of simple quantities in the various schemes, we point out similarities and differences between them.
