MINOS Update

An official MINOS paper now reports a $\Delta m^2$ of $3.36 \times 10^{-3}$ $\textrm{eV}^{2}$ for the antineutrinos. This is very similar to the figure quoted last June. The abstract ends with the immortal words:
The MINOS muon neutrino and muon antineutrino measurements are consistent at the 2% confidence level, assuming identical underlying oscillation parameters.


  1. So they see the glass as 2% full instead of 98% empty.

  2. The first version of the paper was more explicit: it said there was a 2 percent chance that neutrinos and antineutrinos matched. I guess some people in the collaboration were not happy with that conclusion.
