- PhD students
- Zhengwen Liu (ERC), member since June 2016I am interested in analytic computations in quantum field theories, with current focus on modern techniques of calculating scattering amplitudes.Robin Marzucca (ERC), member since September 2015PhD student in theoretical particle physics, working on the mathematical structures of scattering amplitudes. Special interest in elliptic polylogarithms.Martin Michel (FRIA), member since September 2016Computation of quark mass effects in Higgs gluon fusion.Bram Verbeek (ERC), member since October 2015PhD student in theoretical physics, interested in the mathematical structure of scattering amplitudes.

- I am involved in the following research directions:

#### FeynRules

An automated framework for BSM phenomenology that allows one to compute Feynman rules from a Lagrangian.

External collaborators: Céline Degrande (CERN) Benjamin Fuks (Jussieu).

#### Mathematical Structure of Feynman Integrals and Scattering Amplitudes

Analytic and algebraic properties of multi-loop integrals are analysed in the view of devising new mathematical tools for precision computations in QFT.

External collaborators: Samuel Abreu (Universität Freiburg) Ruth Britto (Trinity College Dublin) Einan Gardi (University of Edinburgh).

#### Multi-loop scattering amplitudes in N=4 Super Yang-Mills

Multi-loops scattering amplitudes in N=4 Super Yang-Mills are analysed in the light of the integrability of the theory in the planar limit.

External collaborators: Vittorio Del Duca (ETH Zurich & INFN Frascati) Lance Dixon (SLAC) James Drummond (University of Southampton) Falko Dulat (SLAC) Georgios Papathanasiou (SLAC).

#### Precision Phenomenology at the LHC

Higher order corrections to key processes at the LHC (Higgs,...) are computed to higher orders in perturbation theory.

External collaborators: Babis Anastasiou (ETH Zurich) Vittorio Del Duca (ETH Zurich & INFN Frascati) Falko Dulat (SLAC) Elisabetta Furlan (ETH Zurich) Thomas Gehrmann (Universität Zurich) Franz Herzog (Nikhef) Achilleas Lazopoulos (ETH Zurich) Bernhard Mistlberger (CERN).
