### Neutrino Theta Update

The biggest problem with being an intelligent woman in physics is that nobody ever tells her anything. It is one of many, many means to slow her down.

Anyway, here is a new combined constrained range for a non zero $\theta_{13}$ angle, favouring the Chooz result and beginning to disfavour the low estimate of MINOS. Below are the predicted limits for a year from now. At present, a $\sin^2 2 \theta_{13}$ of $0.04$ sits at the lower end of the range.

1. So my new prediction, near the centre of the current range, and inspired by the simplicity of mixing parameters, is:

$\sin^2 2 \theta_{13} = 0.067$

from $\theta_{13} = \pi /24$. I'm sure, however, that we will soon have a better idea of the precise value.
