Has new ghost particle manifested at Large Hadron Collider?
'某些可怕地新的東西'在數據中突然出現，仍有待阿特拉斯探測器來確認
‘Something terribly new’ goes bump in data yet to be confirmed by Atlas detector
Scientists at the Cern nuclear physics lab near Geneva are investigating whether a bizarre and unexpected new particle popped into existence during experiments at the Large Hadron Collider.
Researchers on the machine’s multipurpose Compact Muon Solenoid (CMS) detector have spotted curious bumps in their data that may be the calling card of an unknown particle that has more than twice the mass of a carbon atom.
The prospect of such a mysterious particle has baffled physicists as much as it has excited them. At the moment, none of their favoured theories of reality include the particle, though many theorists are now hard at work on models that do.
“I’d say theorists are excited and experimentalists are very sceptical,” said Alexandre Nikitenko, a theorist on the CMS team who worked on the data. “As a physicist I must be very critical, but as the author of this analysis I must have some optimism too.”
