Scientists at CERN Have Detected A New “Ghost Particle”

Scientists are trying to work out if a strange new particle, dubbed a “ghost particle”, has been detected at CERN’s Large Hadron Collider (LHC) in Switzerland. Using the Compact Muon Solenoid (CMS) instrument on the particle accelerator, the team said they had seen a signal that could be a particle that’s twice the mass of a carbon atom.

It may take another year to find out if this particle is real or not, but as Science Alert notes, even if it is real it’s not exactly physics-breaking. “But it is strange – a mass that has formed where no mass was expected,” they said.

This isn’t the only particle news we’ve had this year. In fact, this isn’t even the only “ghost particle” news we’ve had, because in July, astronomers announced the discovery of neutrinos coming from an energetic galaxy 4 billion light-years away – a slightly different discovery, for sure though.

Perhaps more relevant was the news from September this year, when scientists suggested they “broke the Standard Model” with the detection of ultra-high energy cosmic neutrinos using the Antarctic Impulsive Transient Antenna (ANITA).

In March, there was news of the weirdly named “skyrimon”, a particle with ball lightning-like properties. And also in September, results at CERN hinted at a particle that seemed to defy the Standard Model. Will this latest discovery stand up to scrutiny? Time will tell. But it’s certainly an exciting time for physics at the moment.
