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

Simulation reconstruction @ uf

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

Outlook

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
