A Simple Alternative to Jet-Clustering Algorithms

Understand

I describe a class of iterative jet algorithms that are based on maximizing a fixed function of the total 4-momentum rather than clustering of pairs of jets.

• I describe some of the properties of the simplest examples of this class, appropriate for jets at an $e^+e^-$ machine.
• These examples are sufficiently simple that many features of the jets that they define can be determined analytically with ease.
• The jets constructed in this way have some potentially useful properties, including a strong form of infrared safety.
