|Observables in jet physics are sensitive to both collinear
and infrared logarithms which are resummed by Sudakov
factors. It has been found recently that some observables
(non-global) have correlated infrared 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 here discussed.
