We report on the three Mathematica packageshexagon, CSectors, AMBRE. They are useful for the evaluation of one- and two-loop Feynman integrals with a dependence on several kinematical scales. These integrals are typically needed for LH C and ILC applications, but also for higher order corrections at meson factories. hexagon is a new package for the tensor reduction of one-loop 5-point and 6-point functions with rank R= 3 and R= 4, respectively; AMBRE is a tool for derivations of Mellin-Barnes…

Efficient contraction of 1-loop N-point tensor integrals
A new approach for the reduction of tensor integrals is described. The standard decomposition \`{a} la Davydychev is applied. Integrals with higher indices are then expressed in terms of scalar
New Results for Algebraic Tensor Reduction of Feynman Integrals
We report on some recent developments in algebraic tensor reduction of one-loop Feynman integrals. For 5-point functions, an efficient tensor reduction was worked out recently and is now available as
Applications of FIESTA
TLDR
A new program performing the sector decomposition and integrating the expression afterwards and can be also used in order to expand Feynman integrals automatically in limits of momenta and masses with the use of sector decompositions and Mellin--Barnes representations.
Numerical evaluation of tensor Feynman integrals in Euclidean kinematics
For the investigation of higher order Feynman integrals, potentially with tensor structure, it is highly desirable to have numerical methods and automated tools for dedicated, but sufficiently
Complete algebraic reduction of one-loop tensor Feynman integrals
We set up a new, flexible approach for the tensor reduction of one-loop Feynman integrals. The 5-point tensor integrals up to rank R=5 are expressed by 4-point tensor integrals of rank R-1, such that
