  * CHS jets = “Charge Hadron Subtracted” jets = remove charged PF particles associated to non-primary vertices (remove charged pileup). These are the __default in Run 2__.
  * PUPPI jets = PF constituents have been weighted/removed by an algorithm (PUPPI) which is designed to remove pileup contamination (more info in PU section). These are the __default in Run 3__.
