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; - ​Particle Data Group identifier

Int_t Status; - generator specific status code: ​HepMC status codes, ​Herwig status codes, ​Herwig++ status codes, ​Pythia status codes

Int_t Charge;

Float_t Mass;

TLorentzVector Momentum, Position; - momentum and position stored in form of ​TLorentzVector data type
