Moving Closer To A Potential Fifth Force Of Nature

A few months ago, we reported on a curious experimental result where Hungarian scientists detected an unpredicted new particle in the nuclear decay of some beryllium atoms. Some US-based theoretical physicists looked into it and think this data is evidence for a potential new force of nature.

The team has now released a follow-up paper, published in Physical Review Letters, in which they construct the mathematical model for this force. This model is an extension of the current theory, known as the Standard Model of particle physics, and could help explain things like dark matter, which is not predicted by the theory so far. The researchers believe that this is the first hint of a new force.
