  1. Muon Event Model Summary of the status of the C++ persistent view of the muon system Work done by: Rome Digitisation and backgroundRio (+CERN) Muon IDCERN XML geometry and response parameters and detector reconstruction David Hutchcroft

  2. Event model diagrams for the Muon system and Muon PID Muon PID in muon system Muon PID MuonID Digitisation and reconstruction Generator Classes are in blue 1-N relation 1-1 relation MCParticle 1-1 relation Reconstructed data MuonCoord Reconstructed tracks TrSimpleTrack GEANT tracking 1-N relation 1-N relation Reconstructed data MCMuonHit MuonCoord Raw data After digitisation MuonDigit MCMuonDigit Match through equal MuonTileID David Hutchcroft

  3. OO-DST Output stored in the DST for physics: • ~40 MuonID objects, one for each track • ~200 MuonCoord used to make the MuonID objects (~800 in total created) • A reference table between stored MuonCoords and MCParticle objects • All other objects will be dropped, could be recreated by rerunning the reconstruction David Hutchcroft

  4. Schedule • The plan is to have a first OO-DST by the end of April • Output from all detectors should be ready by then • Complete physics analysis commissioned on a sample decay: Bd J/ () Ks() • The physics tools and sub-detector code should be ready before June • Physics analysis developed over the summer for physics/light TDR in September David Hutchcroft

  5. Status • The converter from the MURW bank (raw GEANT information) is done • Digitisation is not yet complete: see Roberta's talk • Converter from MULC bank to make MuonDigits directly is done • Muon reconstruction is done • Muon identification is not ready yet, converting from code that used MURW as input David Hutchcroft
