Tools
* pySecDec: a program to factorize the poles from dimensionally regulated parameter integrals and to evaluate them numerically. It can be used for multi-loop integrals as well as other multi-dimensional parameter integrals.
- program

- former members: Sophia Borowka, Jonathon Carter, Stephan Jahn, Tom Zirke
* ggHH: NLO corrections to Higgs boson pair production with full top quark mass dependence, including anomalous couplings
* GoSam: a program to generate and evaluate multi-leg one-loop amplitudes, within and beyond the Standard Model.
* golem95: one-loop library of scalar and tensor integrals (written in Fortran95).
* eerad3: computes the QCD contributions to event shapes and jet rates in electron-positron annihilation at parton level to order $\alpha_s^3$. For three-jet production and related observables, this corresponds to NNLO corrections.
