Physicists observe neutrinos coming from “the sun, cosmic rays, supernovae and other space objects, as well as particle accelerators and nuclear reactors,” writes Phys.org. But the remaining goal is to observe the neutrinos inside. ”Collider Particle Accelerator (Direct two particle beams).
now it has Achieved using the Neutrino Detector at CERN’s Large Hadron Collider (LHC) was conducted in Switzerland by two different research collaborations.
– FASER (forward search experiment)
– SND (Scattered Neutrino Detector) @LHC
Phys.org claims that the two results “could open up important new avenues for the study of particle experiments.”
The results of two of their studies were recently published. published in physical review letter. “Neutrinos are very abundantly produced in proton colliders such as the LHC,” Cristovao Vilela, a member of the SND@LHC collaboration, told Phys.org. “However, until now, these neutrinos have never been observed directly. Neutrinos are very difficult to detect because their interaction with other particles is very weak, and therefore elementary particles It is the least studied particle in the standard model of physics…”
“Particle colliders have been around for more than 50 years and have detected every known particle except neutrinos,” Jonathan Lee Feng, co-spokesman for the FASER collaboration, told Phys.org. . “At the same time, every time neutrinos are discovered from new sources, such as nuclear reactors, the sun, the Earth, or supernovae, we have learned something very important about the universe. As part of our recent research, , we decided to detect for the first time neutrinos produced in particle colliders…
“These neutrinos have high magnetic flux and high energy, and are much more likely to interact, so we could use very small and cheap detectors built in a very short period of time to detect We were able to detect 153,” Feng explained. “Until now, particle physics was thought to be divided into two parts: the high-energy experiments needed to study heavy particles such as top quarks and the Higgs boson, and the high-energy experiments needed to study neutrinos. This work shows that neutrinos can also be studied in high-energy experiments, bringing together high-energy and high-intensity frontiers.”
The neutrinos detected by Feng and the rest of the FASER collaboration have the highest energies ever recorded in a laboratory environment…Cristovao Vilela, a member of the SND@LHC collaboration, said: “The observation of colliding neutrinos opens the door to new measurements,” he said. This leads to the more fundamental mysteries of the Standard Model of particle physics, such as why there are three generations of matter particles (fermions) that appear to be exact copies of each other in all respects except mass. It helps to understand some of the “Our detector is placed in a blind spot for his large-scale LHC experiment, so our measurements also contribute to a better understanding of the structure of the colliding protons. ”
