Power corrections in collider processes (B1e*)

• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: since 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 396021762

In this project we will study perturbative and non-perturbative aspects of power corrections to collider processes. Specifically, we plan to develop novel techniques to extend the renormalon calculus to processes with non-abelian interactions, we envisage improving effective-field-theory methods for resummations at sub-leading power, and we will compute power-suppressed terms to cross sections and kinematic distributions that are needed to improve slicing techniques for fixed-order QCD calculations.
