FeynCalc 10.2 and FeynHelpers 2: Multiloop calculations streamlined
Vladyslav Shtabovenko
We present new versions of the Mathematica package FeynCalc and the FeynHelpers add-on that represent an important contribution to the collection of public codes for semi-automatic…
form factors at large recoil: SCET analysis and a three-loop consistency check
Guido Bell, Philipp Böer, Thorsten Feldmann +2
The double-logarithmic series of non-relativistic form factors at large recoil is governed by a coupled set of integral equations, reflecting an intricate interplay…
Complete next-to-next-to-leading order QCD corrections to the decay matrix in -meson mixing at leading power
Ulrich Nierste, Pascal Reeck, Vladyslav Shtabovenko +1
We compute next-to-next-to-leading order corrections to the decay width difference of mass eigenstates and the charge-parity (CP) asymmetry in flavour-specific decays…
form factors at large recoil: Interplay of soft-quark and soft-gluon dynamics
Guido Bell, Philipp Böer, Thorsten Feldmann +2
We perform an all-order analysis of double-logarithmic corrections to the so-called soft-overlap contribution to heavy-to-light transition form factors at large hadronic recoil. Sp…
Current-current operator contribution to the decay matrix in -meson mixing at next-to-next-to-leading order of QCD
Marvin Gerlach, Ulrich Nierste, Pascal Reeck +2
We compute next-to-next-to-leading order perturbative corrections to the decay width difference of mass eigenstates and the charge-parity asymmetry in flavour-specific…
FeynCalc 10: Do multiloop integrals dream of computer codes?
Vladyslav Shtabovenko, Rolf Mertig, Frederik Orellana
In this work we report on a new version of FeynCalc, a Mathematica package widely used in the particle physics community for manipulating quantum field theoretical expressions and…
