Hi Expert,
I have some questions about the truth parent particle, I have used a root file for Higgs decaying to 2 gammas, there are some kinematic parameters and I would like to produce the gamma that comes from Higgs, and as I understood that I should look at the parent particles for that. but the problem for me is when I open the root file and I look at this photon truth parent I haven’t found the kinematic parameters that I want, please find attached
the screen of my TBrowser:
Knowing that the print of this branch is:
…*
