In the search for a new elementary particle that would transmit a previously unknown force, it’s been an 11-day roller coaster ride at Fermilab’s Tevatron, the premiere U.S. atom smasher. And the ride’s not over yet.

At a conference in Blois, France, on May 30, Giovanni Punzi of the University of Pisa and the INFN in Italy raised hopes that one of the two particle detectors at the Tevatron, known as CDF, might indeed have discovered a new elementary particle. With the analysis of additional...
