...ose tool for IBP reduction (the built-in TARCER [10] is suitable only for 2-loop self-energy type integrals), this omission can be compensated by using one of the publicly available IBP-packages (FIRE[50], LiteRED[55], Reduze[56], AIR[57]). However, one should keep in mind that such tools usually expect their input to contain only loop integrals with linearly independent propagators that form a basis....

...used at some stages of NNLO [48, 49] calculations. Indeed, FeynCalc can be well employed for small or medium size multi-loop processes if one connects it to suitable tools for IBP-reduction (e.g. FIRE[50]) and numeric evaluation of multi-loop integrals (e.g. FIESTA [51] or SecDec[52]). Last but not least, FeynCalc can be also useful for educational purposes. The possibility of easily getting hands-on ...
