What’s so Hard About Neutrino Physics (from the Accelerator Standpoint)?
•Probability that a proton on the AP target will produce an accumulated pbar:
  .000015 (1.5E-5) •Probability that a proton on the MiniBooNE target will result in a detected neutrino:
  .000000000000004 (4E-15) •Probability that a proton on the NUMI target will result in a detected neutrino at the MINOS far detector:
     .000000000000000025 (2.5E-17)

•Þ Need more protons in a year than Fermilab has produced in its lifetime!!
