#988 new Bug

Non-isolated muon disappear

Description

Dear Delphes Authors,

I have generated events with two collinear muons. But I can not find those two muon in final objects like EFlowtrack in Delphes output. Neither it is reconstructed as a jet.
How can I recapture the information of the muon-jet?

Thank you very much in advance!

Cheers,
xun

Could you please attach a small hep or hepmc file, so that I can rerun the reconstruction sequence?

Thanks

Thanks

Here I attached the hep file in MG5.
The process is gg > h > x0(->ee) x0(->mumu).

Cheers.

Your muons are not stable, they seem to always decay to evv.
You can probably fix this in in your event generator...

Hi! Thank you very much. I am very sorry for making such an stupid mistake…
The muon indeed appearing in the EFlowTrack when I turn off the muon decay.

I am also wondering why the electron from muon decay does not show up in the EFlowtrack?
