Radja Boughezal's research interests cover many area of particle physics, including QCD and electroweak precision observables, Higgs phenomenology, and new calculational techniques for precise predictions of collider observables.

Most results from experimental particle physics are currently well described by the Standard Model. It encompasses the electromagnetic, weak and strong interactions and has been successfully tested to an impressive level. Our main tool in obtaining verifiable predictions based on this model is perturbation theory. Leading-order results in the Standard Model do not provide a satisfactory description of experimental data; higher order quantum corrections are needed. The work of Radja Boughezal focuses on developing new analytical and numerical calculational techniques to obtain such high-precision predictions for collider observables within the Standard Model and its possible extensions.
