QFT for Collider Physics
Precision calculations for collider physics


The main field of research of QFT@COLLIDERS is the application of Quantum Field Theory techniques to the phenomenology of present and future colliders. Important searches and experimental measurements, at modern particle accelerators at energy and intensity frontiers, require the calculation of higher-order corrections to a variety of scattering processes in gauge theories of fundamental interactions. Moreover, such calculations can be implemented in the form of Monte Carlo event generators, in order to allow for a systematic and meaningful comparison between data and theory. In the forthcoming years an increasing level of theoretical precision will be required to fully exploit the high quality of future data collected at the LHC and high-intensity e+e- machines. Searches for new physics phenomena often requires the accurate simulation of standard model background, and setting limits on the parameter space of new physics models also require an accurate modeling of the new physics signal. Studies of the newly found Higgs boson, and in particular the measurement of its couplings, requires both a highly accurate simulation of the production and background processes, Precision measurements of Standard Model parameters, in combination with accurate theoretical predictions, may open the way to the detection of fundamental physics phenomena not yet discovered, even if the present lack of clear direct new physics signals will persist at the LHC. Furthermore, the synergy between the research at the energy and intensity frontiers may allow to deeply probe the SM and eventually unravel the existence of new physics beyond it.
