European physics lab CERN told plans of a new trial to look for particles related to dark matter which is believed to make up some 27 percent of the universe said Tuesday.
The European Organization for Nuclear Research (CERN) said the new experiment was “designed to look for light and weakly interacting particles.” CERN houses the Large Hadron Collider (LHC) that is a giant laboratory across a 27-kilometre (17-mile) tunnel spanning the French-Swiss border.
Scientists described ordinary matter includes stars, gases, dust, planets and everything on them — accounts for only five percent of the universe. And that dark matter as well as dark energy account for the rest and scientists have unable to perceive whichever.
Dark matter is an enigmatic matter which is perceived through its gravitational pull on other objects in the cosmos and is yet to be perceived optically. “Some of these sought-after particles are associated with dark matter,” a statement from CERN said.
“They may travel hundreds of meters without interacting with any material before transforming into known and detectable particles, such as electrons and positrons. The exotic particles would escape the existing detectors along the current beam lines and remain undetected.”
CERN has come up with a new instrument known as FASER to address the problem, which can perform highly-sensitive searches and is able to look for such particles.
“Although the protons in the particle beams will be bent by magnets around the LHC, the light, very weakly interacting particles will continue along a straight line and their ‘decay products’ can be spotted by FASER,” CERN added.
The goal is to hunt for theorized particles including aptly named dark photons and neutralinos, whom are also in tangent with dark matter. Experiments were expected to start in succession between 2021 and 2023.
The LHC was used to prove the existence of the Higgs Boson in 2012 — labelled the God particle — which permitted scientists to make great progress in understanding how particles acquire mass.
