Description
In this talk, I will show how ambiguities related to solutions of renormalisation group equations (RGEs) can contribute significantly to systematic uncertainties of theoretical predictions for physical observables. I will discuss a general method to estimate these systematic effects using techniques inspired by soft-gluon and transverse-momentum resummation approaches. As application cases, I will consider the evolution of strong coupling, collinear parton-distribution functions (PDFs), and transverse-momentum-dependent distributions (TMDs). Finally, I will present the implications for precision observables in hadron-collider processes.
