Reactor Data Hint At Existence Of Fourth Neutrino

In tunnels deep inside a granite mountain at Daya Bay, a nuclear reactor facility some 55 kilometers from Hong Kong, sensitive detectors are hinting at the existence of a new form of neutrino, one of nature’s most ghostly and abundant elementary particles.

Neutrinos, electrically neutral particles that sense only gravity and the weak nuclear force, interact so feebly with matter that 100 trillion zip unimpeded through your body every second. They come in three known types: electron, muon and tau. The Daya Bay results suggest the possibility that a fourth, even more ghostly type of neutrino exists — one more than physicists’ standard theory allows.Dubbed the sterile neutrino, this phantom particle would carry no charge of any kind and would be impervious to all forces other than gravity. Only when shedding its invisibility cloak by transforming into an electron, muon or tau neutrino could the sterile neutrino be detected.

Definitive evidence “would open up a whole new avenue of research,” says particle physicist Stephen Parke of the Fermi National Accelerator Laboratory in Batavia, Ill.Possible evidence for the sterile particle comes from a mismatch between theory and experiment.

Funny how that happens.

Across your open mind
I trace erratic lines
In motion and in time

I fought a battle won
To the surface of the sun
Through fires on and on

It’s only you
It can’t be me
For I myself refuse to be
I am someone you’ll never know
I am the little neutrino

Solus is not far away
It’s face is brighter than a day
So don’t turn me away

It’s only you
It can’t be me
For I myself refuse to be
I am someone you’ll never know
I am the little neutrino

And now I’m passing through
The one who’s known as you
And yet you’ll never know I do

“Good-night”

Sounds like this fourth neutrino gets very little respect. Like Shemp, or Zeppo, maybe even Joe Besser.

Fourth neutrino? I thought Rubio withdrew?

There is no denying the existence of a Fourth Neutrino and its affect.

Barack Obama : Fourth neutrino or twentieth hijacker.
You decide.

Barack Obama : Fourth neutrino or

no, Barry is a Bugon... unlike neutrinos, even one can cause major damage.

one more than physicists' standard theory allows

There goes the Three Stooges / Marx Brothers theory of physics.

But seriously, observations that deviate from the standard model would be a big deal.

Let me get this straight. You mean there’s more going on than one proton, one neutron encircled by one electron? When did they discover that?

No bother to investigate. Science is ran by consensus now. If enough scientists say something then there is no more debating it.

Thanks blam.

As sterile neutrinos have low mass and might interact in neutrino oscillations at low energies, this looks promising, but just 3 sigma is not enough. It should be 5, as this is hard science not sociology or medical research.

But, there are many theories about sterile neutrinos, and some observations:

Only experiments will exclude the bad ones, although many elegant theories will stay alive too long.
