DUNE ND+FD SIM/RECO ROUND TABLE 2017-09-01 LUKE PICKERING, K. MAHN, J. CALCUTT, D. DOUGLAS
E-BIAS STUDIES: RECAP▸ Investigate how hard detection thresholds can effect a
bias in ERec. ▸ CM Feedback: Interesting studies, but hard to interpret
without more complete detector/reconstruction simulation.

E-BIAS STUDIES: PROGRESS▸ Now using NDTF files: ▸ Efficiency is only really useful from STT
because of 12 hit cut. ▸ Use uBooNE efficiencies as a starting
point for LAr. ▸ Ideas for GAr?
▸ Applying efficiencies/smearing from NDTF files onto generator output with NUISANCE.

E-BIAS STUDIES: PLANS▸ Immediate: Need to also understand calorimetry —
thresholds and resolution. ▸ Where to look for STT/GAr? ▸ σdE/dx(E) for ND280 TPC?
▸ November: ▸ Try and find some nasty fake data that can mimic
CPV because our model is wrong. ▸ For CPV need nue-appearance — Makes simple
fake OA studies a little more fiddly.

DUNE PRISM: RECAP▸ Very preliminary linear combination fits. ▸ CM Feedback: DUNEPrism is a neat
idea and all, but need to show that it is resilient to flux uncertainties and fixes something in fake data fits that a fixed detector can’t.

DUNE PRISM: PROGRESS▸ Built simple fake oscillation analysis
framework into NUISANCE. ▸ Build response matrix from acceptance/
smearing. ▸ Run NOvA style analysis. ▸ Observed and smearing can use
different xsec models. ▸ Tools for shifting energy between
hadronic final states => Produce fake data outside of generator predictions.

DUNE PRISM: PLANS▸ Immediate: ▸ Look into CAFAna and include more statistical tools in
NUISANCE. ▸ Include DUNE beam line uncertainties. ▸ Investigate linear combination oscillated flux fits.
▸ For November: ▸ Aim to show that DUNEPrism can help identify (and
hopefully mitigate) problems in the xsec model that a fixed detector cannot.
▸ Number of positions needed and predicted event rates.
