Parton showering → Hadronization → Jet of color neutral particles

Each particle belonging to a jet is known as a constituent. Each has a 4-vector that can be used for further studies. + +We need a jet algorithm to collect the particles in a shower. This defines a __Clustering +Algorithm__. This algorithm iteratively find the two particles in the event which are closest in some distance measure and combine them. Combine two particles if $d_{ij} < d_{iB}$.
