In the Large Hadron Collider, physicists were first discovered within the framework of the FASER project “Ghost particles” – control signals of neutrinos, Transfers New Atlas.
Neutrinos are basic, electrostatic particles that rarely interact with particles of matter. Because of this, although they are very common, they are difficult to detect – in fact, billions of neutrinos pass through your body right now. Because of this, they are often referred to as ghost particles.
Neutrinos are formed in stars, supernovae, quasars, radioactive decay, and cosmic rays that interact with atoms in the Earth’s atmosphere. For a long time it was believed that particle accelerators like the Large Hadron collision would also create them, but without the right tools, these particles could not be captured.
This “perfect instrument” was established in 2018 and announced the discovery of six neutrino contacts by the end of November 2021.
“This is a step towards a deeper understanding of these elusive particles and the role they play in the universe,” says scientist Jonathan Feng.
The FASER instrument, located 480 meters below the crash site, is similar to film photography. The detector consists of lead and tungsten plates, which are separated by slurry layers. Some neutrinos attack the nuclei of atoms in dense metals, forming other particles that pass through the broth. You can see the marks they leave when the gravy layers are “displayed” like a picture.
“The FASER team, which tested the emulsifier’s performance to monitor collision-generating neutrino interactions, is now developing a new series of experiments with a more complete tool that is much larger and more sensitive,” says Feng.
The full version of the detector, called FASERnu, weighs more than 1,090 kg compared to the 29 kg test. Its increased sensitivity not only allows frequent detection of neutrinos, but also distinguishes their types.
“Given the power of our new inventor and its convenient location on CERN, we expect to be able to detect more than 10,000 neutrino interactions starting in 2022 and at the next release of the collision,” said David Caspar, co-author of the study. . “We will discover the highest energy neutrinos ever made from a synthetic source.”
