Readiness  We are well along in preparation:  We have two different physics-based beam simulations and the standard GEANT4 detector simulation.  Track, shower, and vertex finding algorithms are well advanced.  We have two very different, but equally powerful, ν e identification algorithms, library matching and neural net, and a likelihood-based ν µ identification algorithm.  We have had one successful data challenge and are planning another, which will include the full near detector- far detector extrapolation.  We have established a set of rules for blind analyses.

NuMI Beam  Good progress toward final high intensity configuration.  Metric = (Design + 2*Base)/3  FY14 metric = 3.24 x 10 20 pot  FY15 metric = 3.62 x 10 20 pot  NO ν A nominal year = 6 x 10 20 pot Gary Feldman EMG 11 April 2014 3

Plans for First Results  Data up to the shutdown.  Analysis complete November-December 2014  How much data?  Beam projection is 1.9 x 10 20 pot.  Average mass is 11 kt  Efficiency = 80% for water leaks and other teething problems.  = 1.2 x 10 20 pot equivalent or 20% of a nominal NO ν A year.  In a nominal NO ν A year we expect about 15 ν e events x/÷ 2 depending on the physics parameters and about an equal background, half from misidentification and half from cosmic rays. So we would expect about 3 signal events with 3 background. Gary Feldman NO ν A Collaboration Meeting 4 April 2014 5
