Notable Points about 07a MC

  • The cut on outer detector hits has been changed

from nhitac<10 to nhitac<16, this is to bring it in line with SK-III standards.

  • Changing the nhitac cut has virtually no effect on

sensitivity

  • Mine-san made a new version of POLfit to reduce

backgrounds with minimal loss of signal.

  • All sensitivity plots are for 90% one sided

confidence level

K2K-style cuts.

  • remove cosine cut
  • remove pi0 likelihood cut
  • make pi0mass cut p dependant:
  • pi0mass increases linearly from 50 to 100

for momentum between 0 and 300 MeV.

  • For p>300 MeV, the cut is simply

pi0mass<100.

Cuts A la Josh

  • Cosine cut is still eliminated
  • pi0likelihood cut is back
  • the k2k style pi0mass cut is now:
  • pi0mass increases linearly from 50 to 100

for momentum between 0 and 300 MeV.

  • For p>300 MeV, the cut is simply

pi0mass<100.

T2K-SK Cut Details cut true fiducial fiducial (FV) nhitac cut (FC) evis cut

  • ne ring

e-like no μ→e decay cos cut π0 mass π0 likeness Eνrec cut Description MC vector (true) information shows the interaction vertex is > 2m from the wall. This indicates the event is fiducial. We normalize event rates to the true fiducial rate, but do not cut on this parameter. The reconstructed interaction vertex is > 2m from the wall. This is the fiducial volume cut. The number of hit PMTs in the OD PMT cluster with the highest charge, nhitac <16. An event passing this cut is considered to be fully contained. The total visible energy in the ID is > 100 MeV/c. This does very little for signal/background separation, but it eliminates non-events. Only one ring is detected by the regular ring-finding algorithms. The one detected ring is determined to be e-like. No μ→e decay is detected in a time window after the event. This eliminates muons (and pions) which are mis-identified as electrons, but which decay into electrons (possibly through muons) at a later time. The angle between the reconstructed electron momentum and the ν beam direction has cosθ<0.9. This eliminates many of the coherent scattering events (which are very forward directed) The POLfit reconstructed π0 mass < 100 MeV. POLfit will attempt to fit a second ring to the data, in case it was missed. Assuming this second ring is valid, the π0 invariant mass is calculated. The cut eliminates π0 decay events where one of the rings was initially mis-identified (π0 mass = 135 MeV). log(L(π0)) -log(L(e)) < 80. POLfit gives likelyhoods to whether the event is π0-like or e-like. This cut eliminates events which are significantly more π0-like than e-like, thus cutting more π0 decay events. Neutrino energy can be reconstructed from the lepton momentum and known beam direction. Events pass this cut if the Eνrec is between 0.35 and 0.85 GeV. The maximum probability for νμ→νe oscillation

  • ccurs for neutrinos in this energy range. The beam energy (at this off-axis location) is peaked here.

This cut is only necessary for a counting experiment; this parameter could also be fitted.
