May the four be with you: Novel IR-subtraction methods to tackle NNLO calculations
W. J. Torres Bobadilla, G. F. R. Sborlini, P. Banerjee +21
In this report, we present a discussion about different frameworks to perform precise higher-order computations for high-energy physics. These approaches implement novel strategies…
Dimensional schemes for cross sections at NNLO
Christoph Gnendiger, Adrian Signer
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…
Small-mass effects in heavy-to-light form factors
T. Engel, C. Gnendiger, A. Signer +1
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 t…
in FDH
C. Gnendiger, A. Signer
We investigate the regularization-scheme dependent treatment of in the framework of dimensional regularization, mainly focusing on the four-dimensional helicity scheme (FDH…
To , or not to : Recent developments and comparisons of regularization schemes
C. Gnendiger, A. Signer, D. Stöckinger +16
We give an introduction to several regularization schemes that deal with ultraviolet and infrared singularities appearing in higher-order computations in quantum field theories. Co…
Regularization-scheme dependence of QCD amplitudes in the massive case
Christoph Gnendiger, Adrian Signer, Andrea Visconti
We investigate QCD amplitudes with massive quarks computed in the four-dimensional helicity scheme (FDH) and dimensional reduction at NNLO and describe how they are related to the…
