Fermilab’s Tevatron collider officially retired in 2011 after a long and glorious history of scientific discovery. But the data from its final run is still yielding potentially exciting results. Physicists from the DZero collaboration have announced the discovery of a new particle, believed to be part of an exotic family called “tetraquarks.”

“At first we didn’t believe it was a new particle,” DZero co-spokesperson Dmitri Denisov told Symmetry magazine. “Only after we performed multiple cross-checks did we start to believe that the signal we saw could not be explained by background or known processes, but was evidence of a new particle.” A paper describing their analysis has been submitted to Physical Review Letters.
