Particle physics is entering an exiting phase with the recent start of the Run 3 data taking at the LHC experiments. In this phase precision measurements will test the Standard Model of particle physics even further. Of particular interest are measurements related to the Higgs boson and the vector bosons as these are highly sensitive to new physics. This is of special importance as on the one hand the Standard Model is valid up to energies higher than had been expected. On the other hand it leaves several fundamental questions open, puzzling the scientific community for quite some time now: (i) What causes the flavour structure of the Standard Model fermions? (ii) Is there a unification of the fundamental forces as indicated by the underlying mathematical structure? (iii) What is the nature of the observed dark matter relic density? (iv) What causes the observed baryon asymmetry of the Universe? (v) Is only one Higgs field driving electroweak symmetry breaking? Does its potential have the simple form assumed in the Standard Model? What is the dynamical origin of its form and is it linked to the flavour problem raised in the first question? A coordinated and combined effort of theory and experiment is required to answer these questions. We will tackle them by focusing on: precision tests of the Standard Model at the LHC and prospective future colliders, the search for physics beyond the Standard Model at present and future colliders, and the development of field-theoretical methods and tools. It is the aim of the research training group to train a new generation of doctoral researchers with a focus on the connection between theory and experiment and equipping them with modern methods and techniques. The doctoral researchers shall be motivated and inspired by neighbouring fields of research to explore the fundamental structures of physics. The doctoral researchers are coached by a thesis committee and are involved in international collaborations. They can foster international contacts in an extended stay abroad and broaden at the same time their scientific horizon. They attend lectures, the RTG summer school, seminars, external schools and conferences. Moreover they have the opportunity to organise events like mini-workshops themselves. In addition, they benefit from the opportunities offered by the JMU Research Academy.
