Scattering Amplitudes in Quantum Field Theory

Prof. Simon Badger received his doctorate in theoretical physics in 2006 from Durham University in the UK. He has held a number of research appointments including the Niels Bohr Institute, CERN, the University of Edinburgh and Durham University. He joined the University of Turin as associate professor in 2020. He works on multi-loop scattering amplitudes in the Standard Model and precision LHC phenomenology. He was awarded a Consolidator Grant from the European Research Council for the project "High precision multi-jet dynamics at the LHC" in 2018.Prof. Dr. Johannes Henn received his doctorate in physics from Lyon University in 2008, and has held research appointments at Humboldt University Berlin, the Institute for Advanced Study Princeton, and Mainz University. In 2018, he was appointed to the Max Planck Institute for Physics as a Director. He works on mathematical structures in quantum field theory, with a focus on applications to multi-loop scattering amplitudes. In 2017, he received a Consolidator Grant from the European Research Council with the project "Novel structures in scattering amplitudes".Prof. Dr. Jan Plefka studied physics at the TU Darmstadt and Texas A&M University receiving his doctorate in theoretical physics from Hannover University in 1995. He held research appointments at City University New York, NIKHEF Amsterdam and the Max-Planck Institute for Gravitational Physics in Potsdam. In 2006 he was appointed as associate and 2011 as full professor for theoretical physics at Humboldt-Universität zu Berlin. He works on aspects of quantum field theory and gravity, with a focus on scattering amplitudes, gauge-gravity dualities, hidden symmetries and applications of amplitude techniques to classical gravitational wave physics. He received an Advanced Grant from the European Research Council with the project "High-Precision Gravitational Wave Physics from a Worldline Quantum Field Theory" in 2023.Dr. Simone Zoia received his doctorate in physics from Ludwig Maximilians University Munich in 2021, after carrying out research at Mainz University and at the Max Planck Institute for Physics. Currently, he holds a post-doctoral position at the University of Turin. He works on multi-loop scattering amplitudes and Feynman integrals, with a particular interest in their mathematical properties and in analytic techniques. In 2023, he was awarded a Marie Skłodowska-Curie fellowship from the European Research Council.

“This is an excellent textbook on scattering amplitudes, suited very well for M.Sc. or Ph.D. students. … The book is very well suited as a textbook for a one-semester course on scattering amplitudes. Due to the pedagogical style and the exercises it can also be used by students for self-studying.” (Stefan Weinzierl, Mathematical Reviews, August, 2024)
