X(3872) Is Trouble For The Standard Model

Made in Japan:

Scientists have found a sub-atomic particle they cannot explain using current theories of energy and matter.
The discovery was made by researchers based at the High Energy Accelerator Research Organisation in Tsukuba.

Classified as X(3872), the particle was seen fleetingly in an atom smasher and has been dubbed the "mystery meson".

The Japanese team says understanding its existence may require a change to the Standard Model, the accepted theory of the way the Universe is constructed.
