Detailed Description

Implementation of the e+e- Cambridge algorithm (plugin for fastjet v2.4 upwards)

EECambridgePlugin is a plugin for fastjet (v2.4 upwards) It implements the Cambridge algorithm, as defined in

Better jet clustering algorithms Yuri Dokshitzer, Garth Leder, Stefano Moretti, Bryan Webber JHEP 9708 (1997) 001 http://www-spires.slac.stanford.edu/spires/find/hep/www?rawcmd=FIND+j+JHEPA%2C9708%2C001

On construction one must supply a ycut value.

To get the jets at the end call ClusterSequence::inclusive_jets();

Constructor & Destructor Documentation

fastjet::EECambridgePlugin::EECambridgePlugin ( double ycut_in )

inline

Main constructor for the EECambridge Plugin class.

It takes the dimensionless parameter ycut (the Q value for normalisation of the kt-distances is taken from the sum of all particle energies).
