 ====== CEPC studies plan ======
-====== Single Particle: ======
+This page describes the CEPC studies following the plan
+described in the {{:fcs:cepc:observableproposed.docx|observableproposed.docx document}}.
+This plan was agreed between ANL (Sergei Chekanov) and IHEP (Manqi Ruan).
- Type: Electron, Muon, Pion, Photon & Neutron;
- Energy Range: 0.1-150 GeV
+====== Monte Carlo simulation samples ======
- Observable: (As a function of Pola angle & energy)
- Reconstruction efficiency,
- Chance of splitting &
- Energy resolution.
-====== On pure Higgs signal sample: ======
+The current baseline for the SiCEPC detector is SiCEPCv2 [[http://atlaswww.hep.anl.gov/hepsim/soft/detectors/sidcc2/sidcc2.html|described here]].
+Compared to the previous version (SiCEPCv1) described in [[https://arxiv.org/abs/1604.01994|arXiv:1604.01994]], it has improved PFA, tracking and a 3T solenoid field.
+The Monte Carlo samples created for this geometry are located under the tag [[http://atlaswww.hep.anl.gov/hepsim/list.php?find=rfull101|rful101]].
- Z->inclusive, H->di photon:
+====== Single electron studies ======
- Efficiency & sigma/Mean of Higgs invariant mass peak;
- //Checking ECAL & Tracker Material
- Z->invisible,
+Setup analysis environment:
- H->bb, Once Efficiency at 80%, Corresponding efficiency
- H->cc, Once Efficiency at 60%, Corresponding efficiency
- //Checking PFA & Flavor Tagging
- Z->ll, H->inclusive,
+<code bash>
-  Recoil mass spectrum
+wget http://atlaswww.hep.anl.gov/asc/jas4pp/download/current.php -O jas4pp.tgz
-  //Checking Lepton ID & Tracker Resolution
+tar -zvxf jas4pp.tgz
+cd jas4pp
+source ./setup.sh # takes 5 sec for first-time optimization
+</code>
- Z-> vv, H->tautau
+We will study single-particle files posted to [[http://atlaswww.hep.anl.gov/hepsim/list.php?find=eta3_pt150gev|as shown  here]].
-  Tagging efficiency for different H->tautau decay mode
+Let's check file availability:
-  //Checking Tracking, PFA & Impact Parameter
+<code>
+hs-ls pgun_electron_eta3_pt150gev
+</code>
+We will use the reconstruction tag "rfull101" which corresponds to SiCEPC detector.
- Z->ll, H->WW*->lvqq
+Now download the files and calculate track resolution for electrons. We will use this script to make the resolution plot {{:fcs:cepc:track_resolution.py|track_resolution.py}}
- Tagging efficiency for different lepton modes:
-e, 2e +mu, 2mu + e, 3*mu
- //Lepton ID & JER
- Z->qq, H->invisible
+<code bash>
-  Recoil mass spectrum
+hs-get pgun_electron_eta3_pt150gev%rfull101 data/electrons 2 100 # get 100 files in 2 threads in the directory "data/electrons"
-  //JER
+fpad track_resolution.py
+</code>
+The output resolution is
