I generated some zee EVT samples using the gen_zee.py script but when I checked the event, there were PDGID's 0 with the exception with the expected 11 and -11 for electron positron pairs. Checking the PDGID here https://pdg.lbl.gov/2019/reviews/rpp2019-rev-monte-carlo-numbering.pdf there seems to ebe no particle with ID 0. Another fact is that the number of zero id's is exactly half the number of entries in the sample. What is going on? Bellow is the image of an hist plot with the PDGID's @jodafons https://github.com/jodafons @micaelverissimo https://github.com/micaelverissimo
