Researchers at Fermilab, who run the Tevatron particle accelerator, say they've discovered a new particle "anomaly," leading people to think they may have uncovered a new elementary particle or new force of nature. But those working on the project are playing it safe, merely stating that the data is interesting.
Yesterday, we presented a comprehensive guide to the world of subatomic particles, exploring all the known elementary and composite particles. But now it's time to put certainty to one side and explore the wild, mind-bending world of undiscovered particles.
Muons, neutrinos, supersymmetric partners, the infamous Higgs boson - with so many different subatomic particles flying about, it's no wonder theoretical physics can be so confusing. That's why we made this (reasonably) simple guide to all the different elementary particles.
