MCC12 Validation with Pandora Reconstruction Metrics Steven Green on behalf of the Pandora team 14th August 2019 S.Green ProtoDUNE Sim/Reco � 1
Introduction Aim: Use all available metrics to validate the latest reconstruction for use in the MCC12 production. p Primary 𝜌 + Consider all metrics for both data and MC events. Interaction Vertex Reconstruction: In these studies we use Pandora from larsoft v08_27_00, but there have been no changes to the reconstruction logic since.

Data Metrics Now consider the reconstruction metrics we have for data. Comparable performance between MCC11 and MCC12 samples. Discrepancies between MC and data are comparable to what we have seen previously: https://indico.fnal.gov/event/16764/session/17/contribution/72/material/slides/0.pdf Entries MCC12 Production Test Sample - MC 0.40 0.35 0.30 0.25 0.20 MCC12 Production Test Sample - Data 0.15 0.10 0.05 0.00 MCC11 1GeV Beam + Cosmics, SCE 0 1 2 3 4 5 Beam Momentum [GeV] Fraction of Events Reconstruction Efficiency 1.0 Reconstruction Efficiency − 1 10 − 2 0.5 10 3 − 10 0.0 0.0 0.5 1.0 1.5 2.0 2.5 0.0 0.5 1.0 1.5 Momentum [GeV] Opening Angle [rad] � 6 S.Green ProtoDUNE Sim/Reco

MCC12 Production Test Sample - Data Slightly more clear cosmic rays appearing in MCC11 1GeV Beam + Cosmics, SCE MCC12 than in MCC11, with data in the middle. Reconstruction Efficiency � 7 S.Green ProtoDUNE Sim/Reco
Conclusions The performance of reconstruction is comparable between the MCC11 and MCC12 samples. The APA T 0 tagging is working well for both MC and Data. The Pandora reconstruction is ready for the production to proceed. Thank you for your attention! � 8 S.Green ProtoDUNE Sim/Reco
