Different cuts to present Josh Albert

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.
