Repository and example code how to use the HPTTopTagger

The HPTTopTagger algorithm reconstructs hadronically decaying top quarks and is specifically designed for high top quark transverse momentum (>1TeV) where calorimeter granularity prevents the separate detection of the individual decay products.

The HPTTopTagger uses tracks of charged particles (or a combination between E-cal and tracks) inside a fat jet. The tracking information is complemented by the calorimeter measurement (Hcal + Ecal + tracks) of the fat jet energy to eliminate the sensitivity to jet-to-jet fluctuations in the charged-to-neutral particle ratio. The algorithm is based on FastJet jets and their respective cluster sequences.

An example how to use the code is in included in the source file.
