There is no quick answer to your question. I suggest you look at these tips:
You can also learn from LXeUserTrackInformation and LXeUserEventInformation in examples/extended/optical/LXe/
None of these examples does exactly what you want to know, but I am pretty sure that by following these tips and examples, you can store and retreive the parent particle of a Cerenkov photon, that parent particle's track length, and how many Cerenkov photons it produced (you need to count that yourself also). - The central problem is that G4Track is a transient class and any information attached to it or its G4VUserTrackInformation must be transfered over to its secondaries (the Cerenkov photons) or else the information is lost when the G4 navigator is finished tracking that instance of G4Track.
