Exclusive Jet Study With Kt, AntiKt and Cambridge Aachen Jet Finders

  • Reference used to calculate bin width with respect to Jet Energy Resoultion (Calculated using dijet sample): Jet_Energy_Resolution.eps

  • Exclusive Kt Jet Algorithm:

This process ends when all dij and diB are above the dcut value
>

This process ends when all dij and diB are above the dcut value.

The dcut variable again varies when considering an inclusive or exclusive event.

When looking at an exclusive n-jet event.

dcut = Ptmin^(2)

This maintains the jet algorithm ability to factorize the initial-state of the collinear singularities, which allows you to obtain a finite cross-section.

When looking at an inclusive jet event.

dcut = Et^(2)

AntiKt Jet Finder

Changed:
<
<
The Anti-Kt Algorithm follows the same procedure as the Kt algorithm explained above. The difference between these two algorithms is the dij and diB definitions.

The Anti-Kt Algorithm follows the same procedure as the Kt algorithm explained above. The differences between these two algorithms are the definitions for dij and diB.
  dij = min(1/P^2ti,1/P^2tj) ΔR ^2ij / R
