Description

Observables in jet physics are sensitive to both collinear and infra-red logarithms which are resummed by Sudakov factors. It has been found recently that some observables (non-global) have correlated infra-red singularities which are not of Sudakov type but are formally the same as the ones present in small-x physics (BFKL equation). Physics, however, is quite different. An example is discussed here.
