FastJet 3.4.2
05 - using e+e- algorithms

illustrate the use of e^+ e^- algorithms

They mostly differ from the pp algorithm by the fact that rather than using a radius parameter and inclusive jets, they use exclusive jets in one of the following ways:

  • a fixed number of them
  • with a dcut
  • with a ycut

Note that natively, FastJet includes the kt (ee_kt_algorithm) and genkt (ee_genkt_algorithm) algorithms. Others (like Cambridge for e+ e-, Jade or SISCone in spherical coordinates) are available as plugins (see
