====Subject ==== 

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.
