== Particle Candidate Class ==

Delphes' {{{Candidate}}} class is inspired by the !BaBar's {{{BtaCandidate}}}:

http://www.slac.stanford.edu/BFROOT/www/doc/workbook/eventinfo/eventinfo.html#btacand

{{{Candidate}}} can represent various levels of processing, various data types:
 - generated particle,
 - reconstructed object,
 - combination of candidates.

The definition of the {{{Candidate}}} class can be found in
{{{
classes/DelphesClasses.h
}}}

Here are the most interesting fields of the {{{Candidate}}} class:

{{{Int_t PID;}}} - [http://pdg.lbl.gov/2012/mcdata/mc_particle_id_contents.html Particle Data Group identifier]

{{{Int_t Status;}}} - generator specific status code: [http://lcgapp.cern.ch/project/simu/HepMC/205/status.html HepMC status codes], [http://webber.home.cern.ch/webber/hw65_manual.html#htoc96 Herwig status codes], [http://home.fnal.gov/~mrenna/lutp0613man2/node49.html Pythia status codes]

{{{Int_t Charge;}}}

{{{Float_t Mass;}}}

{{{TLorentzVector Momentum, Position;}}} - momentum and position stored in form of [http://root.cern.ch/root/html/TLorentzVector.html TLorentzVector] data type
