1) To evaluate the impact of detector performance, smear the neutral hadron resolution in the `ReconstructedParticlesNoMuons` collection and check the impact on the dijet invariant mass resolution. An example can be found [here] (https://github.com/HEP-FCC/FCCAnalyses/blob/master/examples/FCCee/smearing/smear_jets.py):

2) Now smear the impact parameter resolution and evaluate the imapct on the efficiency of selecting two B-tagged jets or two C-tagged jets.

3) **This part can only be on lxplus and for people having the access rights to eos and the analysis dictonary**
In order to produce plots with more statistics using centrally produced samples, we could use already processed large statistics samples.
To do so we re-run the pre-selection over 10 percent of the total statistics [here](http://fcc-physics-events.web.cern.ch/fcc-physics-events/Delphesevents_spring2021_IDEA.php).

5. We now have a simple analyser that can be used to process the signal and background samples, and plot the mass of the $\tau \rightarrow 3\mu$ candidates. For that we need to process the full statistics. In order for you to have access to `/afs/cern.ch/work/f/fccsw/public/FCCDicts/`, we need to add you CERN login to an afs group. If not already provided, please do so.

All samples that have been centrally produced can be found [on this web page](http://fcc-physics-events.web.cern.ch/fcc-physics-events/FCCee/index.php). We use `spring2021` samples (in `Production tags`), and the files made with `IDEA`. If you enter `TauMinus2MuMuMu` and `TauMinus2PiPiPinus` in the search field, you will see the datasets produced for the signal anf the $\tau \rightarrow 3\pi \nu$ background. The first column shows the dataset names, in this case `p8_noBES_ee_Ztautau_ecm91_EvtGen_TauMinus2MuMuMu` and `p8_noBES_ee_Ztautau_ecm91_EvtGen_TauMinus2PiPiPinu`.

To run fccanalyses over these datasets (and not anymore over one test file), the list of datasets to be processed should be inserted in your `examples/FCCee/tutorials/vertexing/analysis_Tau3Mu_stage1.py` :
