We have released our
first Double Chooz paper to the
LANL archive. This, the first new reactor data since the 1990's,
gives a strong indication that the parameter describing the
cross-generational mixing of neutrinos (theta13) is not zero.
The measured spectrum is more consistent with a fairly large value, and when combined with accelerator results rules out a zero value by more than three standard deviations.
Double Chooz makes Prime Time! See white board in background.
