Jet counting and jet vetos are crucial analysis tools for many LHC searches.
We can understand their properties from the distribution of the exclusive
number of jets. LHC processes tend to show either a distinct staircase scaling
or a Poisson scaling, depending on kinematic cuts. We illustrate our approach
in a detailed study of jets in weak boson fusion Higgs production.Comment: 5 pages, 4 figures, 1 table. Text clarified to reflect that we
