C-P violation in neutrinos confirmed

[Blue Emu]

The scientists working on the T2K neutrino analysis project have announced that they now have enough data collected to confirm that neutrino oscillations do violate Charge-Parity conservation. This result offers an explanation for the excess of matter over anti-matter in the universe, since C-P violation allows particles to interact according to different rules than their anti-particles.

This result might have been available earlier, had not the Great Tohoku Earthquake (in March, 2011) shut down the experimental complex for several months.

This is actually a pretty big deal, because the Standard Model does not specifically predict C-P violation in neutrino interactions. It doesn't specifically forbid it, either... but this result (if it holds up in further experiments) indicates that the Standard Model is NOT complete.

They did not!

Neither did they confirm CP-violation in neutrinos nor did they announce anything like that.

They did experimentally observe the oscillations from muon neutrinos into electron neutrinos. That oscillation is sensitive to CP-violations and might in a further development of the experiment (or a successor) experiment be used to confirm (or exclude in a certain range) CP-violations in neutrinos. But they are not there yet. This experiment is an important step towards that goal but they are not in a position to make a statement about this - yet.

Neutrino oscillations themselves are already beyond the regular Standard Model, so it doesn't make sense to speak about predictions of the Standard Model in neutrino physics. In fact, neutrino oscillations are the only deviation of the Standard Model ever found, so unless the LHC finds anything interesting (and it doesn't look like its going to do in the near future), neutrino physics is the hottest area of particle physics right now.

Well... I stand corrected.
