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
◆ EECambridgePlugin() [1/2]
|
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).
Definition at line 64 of file EECambridgePlugin.hh.
◆ EECambridgePlugin() [2/2]
|
inline |
copy constructor
Definition at line 67 of file EECambridgePlugin.hh.
Member Function Documentation
◆ description()
|
virtual |
return a textual description of the jet-definition implemented in this plugin
Implements fastjet::JetDefinition::Plugin.
Definition at line 71 of file EECambridgePlugin.cc.
◆ run_clustering()
|
virtual |
given a ClusterSequence that has been filled up with initial particles, the following function should fill up the rest of the ClusterSequence, using the following member functions of ClusterSequence:
- plugin_do_ij_recombination(...)
- plugin_do_iB_recombination(...)
Implements fastjet::JetDefinition::Plugin.
Definition at line 77 of file EECambridgePlugin.cc.
◆ ycut()
|
inline |
Definition at line 75 of file EECambridgePlugin.hh.
◆ R()
|
inlinevirtual |
the plugin mechanism's standard way of accessing the jet radius.
This must be set to return something sensible, even if R does not make sense for this algorithm!
Implements fastjet::JetDefinition::Plugin.
Definition at line 80 of file EECambridgePlugin.hh.
◆ exclusive_sequence_meaningful()
|
inlinevirtual |
avoid the warning whenever the user requests "exclusive" jets from the cluster sequence
Reimplemented from fastjet::JetDefinition::Plugin.
Definition at line 84 of file EECambridgePlugin.hh.
◆ is_spherical()
|
inlinevirtual |
returns true because this plugin is intended for spherical geometries (i.e.
it's an e+e- algorithm).
Reimplemented from fastjet::JetDefinition::Plugin.
