Neutrino ‘clues’ appeared for the first time in the Large Hadron Collider
According to a recent report by the physicist organization network, the International Forward Search Experiment (FRASER) group led by American scientists analyzed data provided by the European Large Hadron Collider (LHC) and discovered for the first time neutrinos on the LHC. ‘Clues.’ The latest research has taken an important step towards a deeper understanding of the elusive properties of neutrinos and their role in the universe.
Research paper co-author Jonathan Feng, professor of physics and astronomy at the University of California, Irvine, said: ‘We observed the interaction between six neutrinos for the first time during the trial operation of the small emulsion detector mounted on the LHC. Previously, scientists had never detected such signs in the particle collider.’
Neutrinos are one of the basic particles in nature. They are electrically neutral, very small, and rarely interact with other substances. There are three known types of neutrinos: electron neutrinos, muzi neutrinos, and Taozi neutrinos. Since neutrinos were first observed in a nuclear reactor in 1956, scientists have detected neutrinos from many sources such as the sun, the atmosphere, and the earth, but they have not yet been detected in the particle collider. The theory holds that most of the neutrinos in the colliders have extremely high energies, and we know very little about the interaction of high-energy neutrinos, so the neutrinos produced in the colliders maybe neutrino research belts. Here comes a new revelation.
The researchers pointed out that the latest findings provide scientists with two key pieces of information. ‘First, it confirmed the correct location of neutrinos on the LHC. second, it confirmed the effectiveness of using emulsion detectors to observe the interaction of these neutrinos.’
The research equipment is composed of lead plates and tungsten plates with alternating emulsion layers in between. During the collision of particles in the LHC, some of the neutrinos produced will hit the nucleus of the dense metal, and the resulting particles will pass through the emulsion layer and leave visible traces. This provides scientists with clues about the energy of the particles and helps them. Determine the type of neutrino.
It is reported that the FRASER team composed of 76 physicists from 21 institutions in 9 countries is combining a new emulsion detector with the FRASER device. David Casper, another co-author of the latest study and co-leader of the FRASER project, said: ‘With the new equipment, it is expected that starting from 2022, we will be able to record the interaction of more than 10,000 neutrinos and will also detect The highest-energy neutrino ever produced from a man-made source.’
Casper said that scientists have only observed pottery neutrinos about 10 times before, and this number is expected to increase by one to three times in the next three years.
