Sample with jet properties for jet-flavor and other jet-related ML studies JetNTuple_QCD_RunII_13TeV_MC

The jets were also required to have pseudorapidity of less than 2.5 (this indicates the jet's position in the detector). For each jet, there are variables describing the jet on a high-level, particle-level and generator-level. There are also some variables describing the collision event and the conditions of its simulation.

All of the variables are saved on a jet-by-jet basis, which means that one row of data corresponds to one jet.</p> <p>The origin of a jet is particularly interesting. This so-called flavor of the jet is obtained from the generator-level particles by a jet flavor algorithm, which attempts to match a reconstructed jet to a single initiating particle. As a consequence, the jet flavor definition depends on the chosen algorithm.

Here three different flavor definitions are available. The ‘hadron’ definition identifies b- and c-hadrons from the jet’s constituents, so it is only useful for b-tagging studies. The ‘parton’ definition extends this to include the light jet flavors (u, d, s and gluon).

Finally there is the ‘physics’ definition, which looks at the quarks and gluons of the initial collision. The ‘parton’ and ‘physics’ definitions both identify all jet flavors, but the former is more biased towards b- and c-quarks. If in doubt, it is recommended to use the ‘physics’ definition.</p>
