Feynman integral reduction using Gröbner bases
Mohamed Barakat, Robin Brüser, Claus Fieker +2
We investigate the reduction of Feynman integrals to master integrals using Gröbner bases in a rational double-shift algebra Y in which the integration-by-parts (IBP) relations for…
to all orders in in the large- limit of QCD
D. Boito, G. das Neves, J. Piclum
In this note, we present the result for the QCD corrections to the decay of the Higgs boson into two photons in the large- limit of QCD, providing the first two terms in the h…
IBP reduction via Gröbner bases in a rational double-shift algebra
Mohamed Barakat, Robin Brüser, Tobias Huber +1
We report on an approach to integration-by-parts reduction based on Gröbner bases. We establish the underlying noncommutative rational double-shift algebra wherein the integration-…
Charm-quark mass effects in NRQCD matching coefficients and the leptonic decay of the meson
Manuel Egner, Matteo Fael, Jan Piclum +2
We compute two-loop corrections to the vector current matching coefficient involving two heavy quark masses. The result is applied to the computation of the decay width int…
Logarithmically enhanced Euler-Heisenberg Lagrangian contribution to the electron gyromagnetic factor
Andrzej Czarnecki, Jan Piclum, Robert Szafron
Contrary to what was previously believed, two-loop radiative corrections to the -factor of an electron bound in a hydrogen-like ion at exhib…
NNLO QCD corrections to the polarized top quark decay
A. Czarnecki, S. Groote, J. G. Körner +1
We compute the next-to-next-to-leading order (NNLO) QCD corrections to the decay of a polarized top quark. The spin-momentum correlation in this quasi tw…
