Abstract

We consider jet-shape observables of the type proposed recently [1, 2] where the shapes of one or more high-p T jets, produced in a multi-jet event with definite jet multiplicity, may be measured leaving other jets in the event unmeasured. We point out the structure of the full next-to-leading logarithmic resummation specifically including resummation of non-global logarithms in the leading-N c limit and emphasising their properties. We also point out differences between jet algorithms in the context of soft gluon resummation for such observables.
