A new "ghost particle" could have been discovered, this time by CERN



A new particle, previously called a "phantom particle", could have been detected in the Larren Hadron Collider (LHC) of the European Organization for Nuclear Research (CERN) in Switzerland. The discovery was made using a tool known as the Compact Muon Solenoid (CMS) on the particle accelerator.

At that time, the team claimed he saw something that might be a particle whose mass is twice as big as a carbon atom. However, the subject does not appear to fit into known theories, which causes some turmoil in the world of science. The research has not yet been examined by colleagues (ie verified in the academic environment), but is available online.

Given the current standards of nuclear physics, this new particle would consist of muons, particles similar to the electron, but with a mass of 200 times greater. It would also have about 1/4 of the mass of the Higgs boson (an elementary particle that emerged theoretically shortly after the Big Bang and can help explain the origin of the universe).

A team researcher who worked with CMS data, Alexandre Nikitenko, told the Guardian that "theorists are excited and experimentalists are very skeptical" about the alleged physical phenomenon. "As a physicist, I have to be very critical, but as an author of this analysis, I must also be optimistic," he added.

It may take some time to find out if this particle is real or not. Science Alert notes even how "weird" is the fact that a mass "where no one expected" was formed. But even if it is not real, it's not exactly a discovery of physics, after all, it is not the first news of the genre that appears.

In July, astronomers announced the discovery of neutrinos from an energy galaxy at about 4 billion light-years away from Earth. Though slightly different, it is still a kind of "ghost particle". And in September, scientists suggested they "broke the standard model" with the detection of extremely large cosmic neutrinos using the Anita instrument.

This standard model is, as the name suggests, a set of factors that contribute to the traditional concepts of particle physics – and these two discoveries in question were not the only ones that challenged it. Turning a bit, more precisely in March, a "strange" ceramic community was revealed, a particle with similar properties to a ray of rays (that is, electric currents circulating within a plasma ball).
