9. 9 Status of the MUON correction framework (I) X. Lopez

10. 10 Status of the MUON correction framework (II) in progress: analysis task for single muons (AliCFMuonSingle.cxx (.C)) fit functions to extract resonances to-do: CF for dimuon continuum (to be moved in PWG3/muon) X. Lopez

11. 11 MUON productions within PDC09 concerning pp @ 10 TeV (I) proposal: minimum bias production several productions with dimuon trigger @ generation: different conditions for alignment (ideal / residual mis-alignment / full mis-alignment) & secret dead maps / cross-sections / polarization motivations: main goal is still to test: the whole analysis framework including the production & analysis of muon/dimuon AOD the HLT (not present in previous productions) min. bias production:  measurement of charm & bottom x-section in a wide p t range (up to about 10 GeV/c) & including the low p t range (  ←  & K needs to be subtracted) dimuon productions:  J/  yield & efficiency measurement  charm & bottom x-section measurement in the US dimuon channel

12. 12 MUON productions within PDC09 simulation framework (II) full simulation: generation  reconstruction  production of ESDs cocktail (AliGenMUONCocktailpp class): charmonia & bottomonia according to parameterizations open heavy flavours from fast generator (AliGenCorrHF class) min. bias PYTHIA event (kPyMb, heavy flavour production switched off) detector configuration: MUON + ITS (SPD) + VZERO + FMD HLT included both in simulation & reconstruction standalone MUON trigger LuT: all p t & low p t geometry: ideal / residual mis-alignment / full mis-alignment secret x-sections for HF & quarkonia and secret dead maps for tracking & trigger & polarization trigger @ generation for dimuon productions (at least 2  in spectro. w/ p t > 0.5 GeV/c)

13. 13 MUON productions within PDC09 for pp @ 10 TeV: status (III) fast generator of heavy quark pairs not yet available: should be ready by end of April (S. Grigoryan @ LPC in April) resonances: parameterization available for J/  (see S. Grigoryan talk @ Oct. PWG3-MUON-EVO) & needs to be done for other quarkonia, x-sections have been calculated strategy: wait until end of April in order to have parameterizations for both open heavy flavours and quarkonia or use PYTHIA (charm x-section underestimated, bottom x-section overestimated) and ready to ask for dimuon productions  one will need to commit a new version for AliGenMUONCocktailpp, AliGenCorrHF & AliGenMUONlib classes  a new aliroot version is needed for the final productions on the GRID
