When we impose a jet veto on a process we are requiring that some region of phase space has a limited amount of hadronic activity. This allows us to discriminate between processes with different initial colour structures, such as the different production methods for a Higgs boson. The simplest case for studying the effects of jet vetoes is dijet production with a rapidity gap. I will discuss how an analytical resummation approach can be used to calculate observables for such a process. I will then compare the analytical results to those of the Herwig++ parton shower and make suggestions for how it can be improved.
