At the Large Hadron Collider, physicists for the first time managed to observe neutrinos — one of the smallest and most mysterious particles that pass through all matter in the world, practically without interacting with it in any way. The "trapped" particles will help scientists better understand the fundamental laws of nature and figure out how the universe came into being.

Previously, physicists could not detect the presence of neutrinos, as they passed right through the detection means. For the first time, scientists from the FASER and SND@LHC collaborations used inexpensive detectors located along the beam line at a distance from the point of collision of protons to observe a particle.

During the test at the Large Hadron Collider, the presence of 153 high-energy neutrinos was recorded, which had never been achieved in laboratory conditions before.

This event is a big breakthrough in elementary particle physics, as it opens up new opportunities for studying the properties and behavior of neutrinos, as well as for testing the Standard Model — a theory describing all the fundamental forces and particles known to science.

Also, thanks to the discovery, physicists will be able to better understand the structure and dynamics of protons, which are the building blocks of matter.
