The gradient flow at large flow times

The gradient flow is a concept which provides a potential bridge between perturbative and non-perturbative physics. The crucial parameter switching between these two regimes is the flow time t.

In this project, you will learn the concepts of the gradient flow and develop methods to extrapolate the perturbative small-t region to the non-perturbative large-t regime. This will help to combine perturbative and lattice results for the determination of fundamental QCD parameters.

Loops on Finite Fields

Quantum effects can tell us something about physics beyond the Standard Model. In order to fully capture such effects, one needs to develop new theoretical methods to calculate loops in Feynman diagrams. Finite Fields have turned out to be a promising avenue.

In this project, you will learn, develop, and apply modern techniques for the calculation of quantum effects in particle physics. You will contribute to the precise theoretical determination of important observables at the LHC.

Effective Field Theories to arbitrary orders

Effective Field Theories can describe physics beyond the Standard Model in a generic way. Their construction is algorithmic, but very cumbersome.

In this project, you will learn the concepts of Effective Field Theories and develop an algorithm for their construction. This will be useful for the interpretation of data collected at the LHC and future colliders, in particular in the light of possible new discoveries.
