Slashdot reader freddienumber13 write:
A series of experiments has shown that tau particles have decayed faster than predicted by the standard model. This has been observed at both CERN and SLAC. This suggests that the standard model for particle physics is incomplete and further research is required to understand this new area of physics.

Nature adds:
One of the key assumptions of the standard model of particle physics is that the interactions of the charged leptons, namely electrons, muons and taus, differ only because of their different masses... recent studies of B-meson decays involving the higher-mass tau lepton have resulted in observations that challenge lepton universality at the level of four standard deviations. A confirmation of these results would point to new particles or interactions, and could have profound implications for our understanding of particle physics.
