The physicist has laid out a new limit on how much Niro is hard to understand – one of the least known particles of the universe – the limits that make other subatomic particles look as big as a black hole by comparing.
In a new result Published This week, in science, researchers have a new limit on the mass of this ITY -Bitsy specifically: not more than 0.45 electrons (EV) for the context, that is, the mass of less than one million electrons, which are locked in a relatively large size of 511,000 and SeQ. ridiculously Lightweight
Neutrinos trillion through your body every second But they are small and are so weak that you don't feel anything.
Niro is the only elementary school. Cooperate with the standard model– Determining the neutrino mass with accuracy can present deep in -depth information in the law of the universe. Neutrino received a mass from Higgs BosonIf other items do? Or have all the new mechanisms to play?
Enter the Karlsruhe Tritium Neutrino or Katrin, a 75 -foot -long vacuum (23 meters long). Scientists check the decay of the radioactivity of isotope in the vacuum room. When the disintegration of isotopes, it will leave electrons and Antineutrinos Researchers cannot measure Antineutrinos directly (they ghosts through the story unlike), but they can (and do) to study the energy of the left electrons to deal with the mass of the Miss particle.
After analyzing the 259 -day data, the Katrin team was able to reduce the best evaluation earlier for the neutrino mass (0.8 ET SeQ.), Almost half but they were not finished. When it's time for 1,000 days to be stomping, the team hopes to push the mass into 0.3 ET SEQ, sometimes even 0.2 and SeQ.
Neutrino still has a lot of tactics, subatomic sleeves. If the Susanne Mertens from Max Planck Institute PutKatthin's collaboration measurement may be a backer into a new physics – and may be better understanding how the first universe has evolved.
In February, other teams detected The most powerful neutrino (Also known as “Ghost details” for their mysterious nature) deep into the Mediterranean Sea, showing that the details may be released from the interaction between the substance and the microwave background – the oldest visible light in the universe.
If the neutrino mass has more – about one volt electrons – Katrin may find the true value. But with a very small size, the new detector and improvement – Katrin ++ – may be used to measure mass with accuracy.
There are certain things in life. But what we can expect reliably is the death of taxes and neutrino that is smaller than ever.
