  8. Running FAMOS 1_1_0 (VII) Run and produce ROOT trees (runs fast!) CMKIN ExFastMuonRoot | tee zprime500mumuLHA-famos.out mv fastmuons.root zprime500mumuLHA-famos.root ========== PYTHIA ExFastMuonRoot -c .orcarc.orig | tee ggZZ-famos.out mv fastmuons.root ggZZ-famos.root Muons in FAMOS

  9. The Muon ROOT Tree Muons in FAMOS

  10. Simulation/Reconstruction @ UF • Four samples of Z’ -> μ+μ- with masses 0.5, 1.0, 1.5, 2.0 TeV generated at UF to study TeV muons and the mass resolution • CMKIN_4_0_0, OSCAR_3_6_1, ORCA_8_6_0 used to produce digis; filter after CMKIN to retain only muons and Final State Radiation  • Root trees produced from digis with Global Muon Reconstructor; set of C++ modules developed to analyze them • The full chain generator -> plots and results is operational • Using FAMOS_1_1_0 Muons in FAMOS

  11. Efficiency for Z’ (i.e. two muons) Muons in FAMOS

  12. Fit for the FAMOS Mass Resolution Strange tails ?! (from December 04 talk) Muons in FAMOS

  13. FAMOS Mass Resolution (Bug fixed) Muons in FAMOS

  14. Mass Resolution as Function of Mass Muons in FAMOS

  15. Outlook • FAMOS is running and starting to be useful for muons of all energies • Need a standard ROOT tree for easier sharing/reuse of analyses and code • TeV muons are a challenge – working on a specialized parametrization for FAMOS in addition to the standard one (the efficiency is a problem) Concentrate on systematic effects e.g. muon simulation and reconstruction for different parts of the detector Muons in FAMOS
