A group of scientists from Hungary recently published a paper that hints on the existence of a previously unknown subatomic particle. The group first reported discovering traces of the particle in 2016, and so they now report extra traces in a different experiment.
If the outcomes are confirmed, the so-known as X17 particle may assist in clarifying the darkish matter, and the mysterious substance scientists believe accounts for more than 80% of the mass within the universe. It could be the service of a “fifth force” past the four accounted for in the usual model of physics (gravity, electromagnetism, the weak nuclear power, and the strong nuclear force).
Most researchers who hunt for new particles use monumental accelerators that smash subatomic particles collectively at excessive pace and have a look at what comes out of the explosion. The most important of those accelerators is the Large Hadron Collider in Europe, the place the Higgs boson—a particle scientist had been looking for decades—was discovered in 2012.
In 2016, they checked out pairs of electrons and positrons (the antimatter model of electrons) produced when beryllium-8 nuclei went from an excessive energy state to a low energy state.
They discovered a deviation from what they anticipated to see when there was a large angle between the electrons and positrons. This anomaly might be best be defined if the nucleus emitted an unknown particle that later “split” into an electron and a positron.
Whereas the results from Debrecen are very attention-grabbing, the physics group won’t be satisfied; a new particle has certainly been discovered until there may be independent confirmation.
