Reading two branches with the same structure

Dear ROOTers,
I would like to ask your help in order a ROOT file that came to me. The structure is that there is a TTree and inside there are two branches. These two branches have the same structure (i.e. both of them contain pt, eta and phi).
How could I read those separately?
I tried the MakeClass method but it ended up saying:

Error in <TTreePlayer::MakeClass>: The branch named etCorr (full path name: CaloJet.etCorr) is hidden by another branch of the same name and its data will not be loaded.

Do you have any suggestions?

Thanks a lot for your time!

Hi,

could you please share the rootfile?
