In the Large Hadron Collider (LHC), physicists have detected ghost particles. These are likely to capture neutrino production signals during a particle collision. This is the raison d’être of the FASER experience. Also called ForwArd Search Experiments, it is, according to the CERN, a scientific study based on research into new particles undiscovered and particles to weak interaction.
Theoretically, from new light particles were discovered in large quantities during the proton-proton collisions at the Large Hadron Collider. In fact, the motive of the physicists who carried out the study lies in the fact that these large quantities had long remained untraceable.
Some particles, especially neutrinos, are the least understood through the standard model of particle physics. From experience FASER, physicists hope to study these interactions through the physics of high energies.
Discovery of six neutrino interactions
Electrically neutral and incredibly light, the neutrinos are particles that often do not have a reciprocal action with other material particles. This is also why they are hardly detectable. It should be noted that they are more a billion to circulate constantly in the body. Because of this eccentric event neutrinos, Atlas News reported that“They are considered to be ghost particles”.
Nevertheless, the FASER experiment installed in 2018, enabled scientists to detect six neutrino interactions. After the discovery, physicists describe that no neutrino was even detected in a particle collider before the FASER project. Jonathan Feng, co-author of the research, explained that “The recent findings represent a significant breakthrough and a step forward in developing a deeper understanding of the properties of elusive ghost particles and their vital role in the universe.”
A new series of experiences in sight
First of all, the FASER instrument works the same as the film photography. Made of tungsten and lead plates, it is equipped with a system of separation by emulsion layers. Indeed, most neutrinos are going to tackle atomic nuclei in dense metals and organize other particles that pass through emulsion previously mentioned.
In addition, one of the authors of the new discovery believes that“After verifying the effectiveness of the instrument and the emulsion detector to observe the interaction with neutrinos, the FASER team will now begin to prepare a series of experiments with complete instruments much more sensitive and larger “.
As a result, the team expects to record more than 10,000 neutrino interactions from here 2022 in the large Hadron Collider (LHC).
