OPERA experiment, scientists Italian National Nuclear Physics Institute (INFN) Gran Sasso Laboratory announced Monday that they had found 730 kilometers away Cerni express themselves within the mu-neutrino calgary sun kiiresesmakordselt tau-neutrino neutrino mystery began with a Nobel Prize worthy experiment, which was conducted by the United States scientist Ray Davis the 1960s. years. Davis noticed that hitting the Earth from the Sun to the far fewer neutrinos than predicted by the then models. There were two possibilities - either the models were wrong, or something unprecedented happened in the meantime neutrinos.
Possible solutions offered in 1969 to Bruno Pontecorvo and Vladimir Gribov, who thought that the different types of neutrinos can change into each other during the oscillation. The neutrino oscillation these phenomena would be able to explain the electron-neutrino calgary sun deficit. Since then, a number of experiments have been conducted, which is observed müüon-neutrino disappearance, confirming the oscillation hypothesis. So far, however, was originally only müüon in a fast-neutrinos to tau-neutrino down. The only way rarer neutrino could occur, the option to change müüon-type tau-type.
Results of the OPERA team was preceded by seven years of preparatory work, and over three years Cerni caused by accelerator neutrino beams. During this time, the Gran Sasso direction to the billions and billions of neutrinos-müüon, 730-kilometer-long path of the particles passing of time takes 2.4 milliseconds. Despite the apparent large number of neutrino neutrino oscillations are rare.
Observation of events makes it more difficult by the fact that neutrinos react very weakly normal substance because the neutrinos participate only in a weak gravitational interactions -and. "Neutrinos do not leave a trace, but the particles of ordinary matter and neutrino calgary sun interactions occur due to do so. If the tau-neutrino detector and mutually influencing, register photographic plates with short, about 1-2 mm in length on tau-lepton track. The latter, however, is unambiguous trace of tau-neutrino interaction, calgary sun "explained Antonio Eradatio, spokesman for the OPERA experiment, the discovery of neutrino Fyysika.ee cent.
Tau-type interactions between the imperative to produce neutrinos at CERN called quick highlight of protons through the bundle, which is accelerated by the target. When the protons hit the target, particles called piionid and kaaonid occur that quickly decompose. The decomposition gives, however, the possibility of neutrino events. In contrast to the charged particles are not neutrinos electromagnetic fields, which are used to guide the particles from other physicists, sensitive. So as soon as neutrinos arise, they can pass through solid kallutamatult aside. That was the reason, since the experimental design of the utmost importance that põrgutatav calgary sun particle accelerator would be targeted at the Gran Sasso laboratory direction.
"It (the experiment, eds.) Success was only possible thanks to the persistence and ingenuity of the international community of physicists that particle beams of specially calgary sun programmed for this experiment. Gran Sasso original design is crowned with success, "said INFN president Roberto Petronzio.
The experiment, the team also shared the characteristic Cerni Director General Rolf Heue r: "This is an important step for neutrino physics. I send my congratulations to the OPERA experiment and the Gran Sasso laboratories, as well as an accelerator at CERN teams. We are all looking forward to their results on the basis of the new physics of broadcloth, lifting. calgary sun "
Seminal findings OPERA team needs more data on the tau-neutrino observations. "First of all, we still need to register with tau-events, before we can say that it is a neutrino ostsillatsioonidega. However, it was the first candidate is very nice, and 98% sure that it was indeed a tau neutrino event, "said Eradano.
The neutrino oscillation direct observation is a sure sign that it is necessary to understand the nature of the neutrino new physics. According to the standard model of particle behavior in narrative lacks the mass of neutrinos. To receive the oscillating neutrinos, at least one
