Description

The higher-order behavior of logarithmically enhanced contributions in non-global LHC observables is very intricate, in particular as double-logarithmic corrections -- so-called super-leading logarithms (SLLs) -- arise first at high orders in perturbation theory.
Their all-order resummation has been understood recently by means of a factorization formula in soft-collinear EFT.
In this talk, I will discuss improvements in the resummation of SLLs, including a renormalization-group treatment with a running coupling constant, as well as corrections from higher-order Glauber exchanges.
