Description
The properties of jets are used in many LHC physics searches. Higgs
searches use jet vetoes and fixed recoil jet multiplicities. Searches
for new physics particles require a careful distinction of decay jets
from QCD jet radiation. We show that the exclusive number of jets
at hadron colliders can be described with two simple patterns: staircase scaling and Poisson scaling. In photon plus jets production we can interpolate between the two patterns using simple kinematic cuts. The associated theoretical errors are well under control. We show how understanding the exclusive jet multiplicities significantly impacts Higgs searches and searches for supersymmetry at the LHC.
