The announcement this week that scientists may or may not have discovered a new subatomic particle has riled up the physics world. So how do we know for sure whether the particle is real or not?
A number of tests in the coming months should point the way:
1. Get more data
The signal comes from the Tevatron particle accelerator at the Fermilab physics laboratory in Batavia, Ill. Scientists noticed a bump in their data — an overabundance of a certain pattern that was not predicted, which could indicate the presence of a never-before-seen particle, scientists say.
The catch is, the pattern could represent a real physical phenomenon, or it could be a statistical anomaly. Scientists say there's a 1 in 1,000 chance the finding is just a fluke. To get a better idea of whether the signal is real, researchers need to sort through more data.
