[Rivet] DressedLeptons in ZFinder

[Christian Gütschow]

Hi all,

just to double check I'm not missing anything here: It's currently not
possible to access the list of DressedLeptons used by the ZFinder, right?
What's the argument against providing this functionality?

Suppose I have an event with three muons that pass a given dressed-level
definition, but only two of them form a Z-boson candidate. If I was to
require *exactly* two muons forming a Z candidate, then I wouldn't be able
to do that using just the ZFinder.

That is, the ZFinder, as far as I can tell, only returns the DressedLeptons
associated with the dilepton candidates, but one couldn't tell whether or
not there was some additional spurious lepton in the event that doesn't
successfully pair up with the others. Unless, of course, the DressedLeptons
projection was added as well, but then why use the ZFinder in this case at
all?

Cheers,
Chris
