Presentation Transcript

  1. Leftover from the TDRs (from Hans) • L0: • Short term: • Dielectron invariant mass plot • Correlation between electromagnetic and hadronic trigger • … • Medium term: • Optimization for tagged events. • Extreme algorithms as a function of luminosity: implementation limit • Multiple tresholds, e- trigger,… • … Trigger Meeting, F.Teubert

  2. Leftover from the TDR (from Hans) • L1: • Short term: • What mbias triggers L1? Pt mistakes, multiple vertices, etc… • Look as a function of the impact parameter. • Medium term: • Can we optimize further the execution time? Do we need backward tracks? • Why L1 is not ~100% efficient? Do we miss the B-tracks? Signed vs unsigned ip • Do we need better VELO resolution? TELL1 could help… • Offline Muons in L1: what rates? As a function of invariant mass, pt (tagging muons),… Trigger Meeting, F.Teubert

  3. Leftover from the TDR (from Hans) • L1-confirmation: • Short term: • Why it works? dp/p, ghosts,… • What mbias events trigger? • … • Medium term (L1-upgrade): • What data from T1-T3 is needed in L1? data/time/money vs gain… • … Trigger Meeting, F.Teubert

  4. Leftover from the TDR (from Hans) • HLT: • Medium term: • Develop an inclusive selection: use of better dp/p, look for secondary vertices,… • Use of RICH in HLT? • Exclusive selection: check channels in TDR, group them and measure time… • Trigger Systematics: • Medium term: • What is the effect of the trigger on the mistag rate? • Example case, psiphi with mistag from Dspi… • … Trigger Meeting, F.Teubert
