As the Large Hadron Collider (LHC) at CERN accumulates increasing amount of data, precise predictions become more and more important. This allows for better determination of standard-model parameters as well as as lower uncertainties and better background estimates, resulting in better potential for (direct and indirect) beyond-standard-model discoveries.
IPhT is involved in the study of scattering amplitudes. Over the past decade, the field of amplitudes has been tremendously active in developing new tools to compute loop scattering amplitudes (spinor-helicity formalism, generalised unitarity, ...). The lab has contributed major achievements in the understanding of these tools and the automation of next-to-leading order (i.e. 1-loop) and is now actively involved in going to higher loop orders. This field is also connected with other more fundamental studies in conformal field theories (e.g. N=4 SUSY Yang-Mills) and graph theories.
The research activities of the IPhT also cover the study of jets and their substructure, another field which has recently gained in importance at the LHC, in particular for searched for new physics. This involves the definition of new substructure tools as well as a first-principles understanding of these tools in QCD. This has deep connections with precision measurements, machine-learning techniques and measurements of the properties of the quark-gluon plasma in heavy-ion collisions.
