Particle physicists have seen a rare happening that may force a rethink of current theories of sub-atomic matter.



After watching more than seven trillion disintegrations of the kaon particle they have seen three peculiar events when they expected to see just one.


At present physicists at the Brookhaven National Laboratory in the US do not know if this is a fluke or points the way to a deeper theory of matter.



The research has been submitted to the Journal Physical Review Letters.



Fluke or breakthrough



The experiment looked at the disintegration of a sub-atomic particle called the K-meson or kaon.



It can decay in a number of ways. One involves it turning into a…
