  1. ND280  - AnalysisSMRD related Analysis Activities Jarek Nowak, Thomas Kutter LSU USB280 Meeting, SUNY August 15, 2008

  2. SMRD related activities • Construct, test and improve fitters • Study SMRD event topologies/responses • Cosmic rays • Beam related events  Develop tools and basis required to do  related analysis

  3. Fitters • Hough transform based fitter • Linear fitter • Both produce reasonable output Todo: • Study performance of fitters  compare, improve, optimize

  4. Matching with other subdetectors • Using the matching TPC and SMRD isolated reconstruction example: development of code to match the SMRD reconstruction results with other detectors in progress. • Match hits, which were not used in the reconstruction with track from inner subdetectors.

  5. SMRD reconstruction status • The SMRD hits are combined to the combo hits • Combo hit: MPPCs on both ends of fiber see hit • The position resolution in all x,y and z are at the same level W. Metcalf – cosmic muons

  6. Numu CC analysis • Several closed meeting – discussion on the topics and task for the numu CC analysis for the Physics Book • Open meeting for the collaboration members interested in contributing to the analysis • Draft outline of the ND280 Physics Book : http://www.nd280.org/analysis/physicsbook/Draft%20Outline • The analysis will be focused on the topology of the events

  7. Goals for the numu group • Prediction of flux in far detector using information from ND280, INGRID and beam information • Study of numu CC interactions: neutrino-nucleon, nuclear effects • 3 levels of the analysis • True MC analysis – identification of limits from physics • Cheating true MC analysis – understand ultimate performance • Reconstructed MC analysis – top level of the analysis • Each level of the analysis will be done for • 1st year configuration – detector and beam • Full configuration

  8. Outline of the CC analysis • Introduction (Yokoyama) • Expected neutrino interactions and event topologies (Sanchez) • Analysis of event topologies (Cervera) • CCQE events (Lindner) • CC1pi events (Nowak) • P0D Analysis (Berger, Wilson) • Deliverbles for oscillation analysis from the CC-numu alanysis (Sanchez, Nowak) • Prediction of number of interaction in SK from the ND280 (Yokoyama) • Detectors requirements and related systematics (representative from each subdetector)

  9. Status • We have • There is an old event topology analysis (Sanchez) which will be revitalized • Cheating analysis for CCQE and CC1pi • There is an analysis of the flux and CCQE in the Ingrid • Reconstruction at various stages • Todo list (near future) • Detail true and cheating MC analysis focused on the event topology • All developed analysis tool should be integrated with the nd280mc
