  1. CC/ND Joint Sessions10/05 MINOS Meeting ND/CC/FD: (Thursday, 13:15-15:15) • Flux normalization (Mike Kordosky, 15 min) started 5 late, give 5 extra minutes, +5 • Quasi-Elastics and Flux (Mark Dorman, 20 min) • Updated on Neutrino Energy vs Batch  (Peter Shanahan, 10 min) • Data Selection in the FD and Related Issues (Niki Saoulidou, 15 min) • FD event selection and data/MC comparisons (David Petyt, 15 min) • FD Fiducial Optimization and CR Backgrounds (Andy Culling, 15 min) • Production of Spectral Data and MC Predictions (Trish Vahle, 10 min) • Giving Us Fits (Jenny Thomas, 20 min) ND/CC (Friday, 10:45-12:15) • Charm/Dimuon Analysis (Costas Andreopoulos, 15 min) • Study of the ND Data/MC for the CC Analysis (Masaki, 20 min) • Data/MC Comparisons in the ND (Trish Vahle, 20 min) • Data/MC in R1.18 for pME, pHE, and LE-10 (Niki Saoulidou, 20 min) • LE CC/Non-CC event rates vs POT (Sanjib Mishra, 5 min)

  2. Plenary Talks • Sat • CC WG (AM 100 min) • Two talks? • MiniBooNE & NuMI (Arevalo, PM, 20 min) • Beam Syst WG (Kopp, 60 min) • Sun • Nuint05 (Costas, 20 min) • ND WG (Sun AM, 60 min)

  3. Flux Normalization (Mike Kordosky, 15 min) ND/CC/FD: (Thursday, 13:15-15:15) • Charm not in NEUGEN • 10% up to 30% * muonic branching fraction • Non stat MC fluctuations many be important • Simple robust test looks good • Needs to think about systematics • Wants to turn this to an absolute measurement • DIS sample – larger effect • DIS cut, y cut • 10-20

  4. Quasi-Elastics and Flux (Mark Dorman, 20 min)

  5. Updated on Neutrino Energy vs Batch  (Peter Shanahan) • Expect couple % effect for shifts between the birficated first bunch (Dharris) • Due to tail of kicker magnet for pbar extraction

  6. Data Selection in the FD & Related Issues (Niki Saoulidou) • Cuts from David (operations session) • Fakes spills (1/3 of seconds without a spill) – random samples • 1112, 122 reco’d, 6 out of time, out of 2e6 reco’d, 106 good events, 73 pass fiducial • Timing cut • Good agreement with 1112 scanned compared to the efficiency corrected numbers • Scan events • Scanned total confusing… 10 , 6 rock, clear up later • Characteristics • Some events early in time • GPS have 200ns timing error (now many sigma?) • Nice to understand (but not a real problem) • Early ND events ??? • Some people see that… (pbar batch or before?) • Strange hit times? 40k ns late? 50> usec • Width of noise window , 500ns time cut for neutrons? 1hit/us randoms. • Examines variables • Low stats, things change due to blinding and oscillations • E/W asym not too bug. • Track PH looks a little different – issues? Prob not • ANN pid variables • Do spill and fake spills with the same reco

  7. FD event selection and data/MC comparisons (David Petyt) • Scan of events • 5.1e19 • 1348 events • R18 – track and event vertex off – (cf Andy) – track fine but vertex at the shower • Fid optimization • 63.3% eff • No bg left • Same 63.6% in MC and data scan • 3.72m cut. • Estimate from out of time muons – 0.03muons/mo • Event variables in data and mC • Norm’d to area • B type plots show effects – others look pretty good • More cluster in data than MC • All the data shoulbe be used for non direvide data

  8. FD Fiducial Optimization and CR Backgrounds (Andy Culling) • Evtx ave of track vtx and shower vtx • Uptimization of fid vs stats and purity • Looked at backgrounds

  9. Production of Spectral Data and MC Predictions (Trish Vahle) • Update from last phone meeting • Compute discrepancies between ND MC and spectral data • Add in Zarko’s error envolope • Fix to pME, pHE target postions for the corrections. • Only after torgt fix • Smaller offsets • Deweighted show looked better but a problem • Still a data & mc problem – linearity • Excess low • Do the 1pe cut • Splitting cut on time before

  10. Giving Us Fits (Jenny Thomas) • Showed results for fit with Trish’s error function

  11. ND/CC (Friday, 10:45-12:15) • Charm/Dimuon Analysis (Costas Andreopoulos, 15 min)

  12. Inverse Muon Decay (Peter Shanahan, 10 min)

  13. Study of the ND Data/MC for the CC Analysis (Masaki, 15 min)

  14. Data/MC Comparisons in the ND (Trish Vahle, 15 min)

  15. Data/MC in R1.18 for pME, pHE, and LE-10 (Niki Saoulidou, 15 min)

  16. LE CC/Non-CC event rates vs POT (Sanjib Mishra, 5 min)

  17. Data/MC Discussion, Comparisons, and Action Items (10 min

  18. CC (100 min) Old issues Horn off ? Horn current variations PID variable performance Energy scan results Reco’d spectral errors Zarko+calib+reco+xsec Fitting David’s Peter’s UCL’s Brian’s Y-dependence calibration (Defer?) FD data results Scans Backgrounds Plots of variables Fid volume optimization Opening the box check list Decision for when we come back after the shutdown ND NEUGEN Update Mike’s stuff Debdatta - tuning Genie Dimuon? IMD? Bunch 2 bunch ND rate vs time RECO Tracking differences Shower differences Late light fixes DIS xsections & QE extrapolations Blessed ND performance plots X and q^2 (Trish) Proposed topical breakdown
