CERN begins the hunt for dark matter

European Laboratory for Physical Research, CERN announced that it plans a new experiment in search of particles associated with dark matter, which is believed to have about 27% of the universe. The experiment will be conducted in the same place, where the Large Hadron Collider - a giant laboratory in the 27-kilometer tunnel on the French-Swiss border. His task will be to find the "light and weakly interacting particles."

CERN begins the hunt for dark matter

How to find dark matter?

Scientists say that the so-called normal matter - from which stars, gas, dust, planets, and everything on them - is only five percent of the universe.

But the dark matter and dark energy make up the rest, and scientists have not yet watched them directly.

Invisible to telescopes dark matter is a mysterious substance that is perceived by its gravitational effects on other objects in space.

In 2010, Buck began high energy protons collide with each other at speeds close to the speed of light. These collisions produce new particles and allow physicists to understand the laws of physics clearly, and thus better understand the universe. But the four major LHC detectors are not suitable for the research of light and weakly interacting particles, such as those associated with dark matter.

"They can travel hundreds of meters without interacting with any material, before becoming a well-known and detectable particles - electrons or positrons. Probably, exotic particles leave the existing detectors and go unnoticed.

To solve this problem, CERN developed a new tool - FASER - which can perform highly sensitive search and detect such particles.

"While the protons in the beams of particles will flex around the LHC magnets, light and very weakly interacting particles will continue to move in a straight line, and their" decay products "can detect FASER", the statement said.

The goal of the LHC - find hypothetical particles, including so-called dark photons and Neutralino, which are also associated with dark matter. The experiment will be conducted in the period from 2021 to 2023.
