Open AccessMay the four be with you: novel IR-subtraction methods to tackle NNLO calculations
In this manuscript, we report the outcome of the topical workshop: paving the way to alternative NNLO strategies (https://indico.ific.uv.es/e/WorkStop-ThinkStart_3.0

Open AccessDimensional schemes for cross sections at NNLO
So far, the use of different variants of dimensional regularization has been investigated extensively for two-loop virtual corrections. We extend these studies to real corrections that are also required for a ...

Open AccessSmall-mass effects in heavy-to-light form factors
We present the heavy-to-light form factors with two different non-vanishing masses at next-to-next-to-leading order and study its expansion in the small mass. The leading term of this small-mass expansion lead...

Open AccessTo \({d}\) , or not to \({d}\) : recent developments and comparisons of regularization schemes
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 si...
