Fermilab Finds New Mechanism for Matter's Dominance over Antimatter

The Large Hadron Collider may be up and running outside Geneva, but the particle accelerator it supplanted as top dog in the particle physics community appears to have a few surprises left to deliver. Data from the workhorse Tevatron collider at Fermilab in Illinois show what appears to be a preference for matter over antimatter in the way an unusual kind of particle decays, according to a new analysis in a Tevatron research collaboration.
