DESCRIPTION:It is well known that perturbative QCD corrections to scatteri
 ng processes contain large double logarithms in the high-energy limit. At 
 leading power\, they are typically induced by soft-gluon exchanges\, and t
 heir all-order structure is well understood. At subleading power\, however
 \, double logarithms often originate from soft-fermion exchanges and exhib
 it a richer and more intricate structure. I discuss recent advances in the
  all-order resummation of such corrections\, from simple QED processes suc
 h as muon–electron scattering to heavy-to-light $B$-meson form factors. 
 I further discuss a systematic framework for their resummation based on as
 ymptotic limits of anomalous dimensions\, and present new results for the 
 resummation of double logarithms in Higgs-boson pair production.\n\nhttps:
