Nobel Prize in Physics was awarded for the confirmation of neutrino oscillations Bashny.Net

On Tuesday morning, the Royal Swedish Academy of Sciences объявила the award of the Nobel Prize in Physics . This year it was awarded to two scientists at the same time: Takaaki Kadzito and Arthur MacDonald. They spent working, prove the hypothesis of neutrino oscillations. In monetary terms, the premium amounted to $ 8 million, or SEK 63 million. Rubles.

Neutrino oscillations - the transformation of one type of neutrino into neutrinos of another type, or in an antineutrino. The theory predicts the existence of the law of periodic change in the probability of finding a particle of a certain grade, depending on the time since the creation of the particle own time. The idea of ​​neutrino oscillations was first proposed by the Soviet-Italian physicist Bruno Pontecorvo in 1957. It is believed that these oscillations are due to the presence of the neutrino mass.

Experiments Kadzito the University of Tokyo (Japan) and Macdonald - at Queens University in Kingston (Canada) showed that the neutrino oscillations do occur. For a long time it was believed that neutrinos - particles are massless, and the Standard Model does not describe their mass or their oscillations. But the theory and evidence of their presence did not break the Standard Model - they fit into it by means of small additions.

Earlier, the Nobel Prize in Medicine was awarded to scientists for combating worms, parasites and malaria .
