Towards the next Kira release
Fabian Lange, Johann Usovitsch, Zihao Wu
The reduction of Feynman integrals to a basis of master integrals plays a crucial role for many high-precision calculations and Kira is one of the leading tools for this task. In t…
Feynman parameter integration through differential equations
Martijn Hidding, Johann Usovitsch
We present a new method for numerically computing generic multi-loop Feynman integrals. The method relies on an iterative application of Feynman's trick for combining two propagato…
30 years, some 700 integrals, and 1 dessert, or: Electroweak two-loop corrections to the Zbb vertex
I. Dubovyk, A. Freitas, J. Gluza +2
The one-loop corrections to the weak mixing angle derived from the vertex, are known since 1985. It took another 30 years to calculate the complete e…
The two-loop electroweak bosonic corrections to
Ievgen Dubovyk, Ayres Freitas, Janusz Gluza +2
The prediction of the effective electroweak mixing angle in the Standard Model at two-loop accuracy has now been completed by the first calculation of t…
