Physicists at the Deutsches Elektronen-Synchrotron (DESY) in Hamburg announced last week that 3 years of smashing positrons and protons together at high energy have produced a handful of collisions too violent to be easily explained in the current picture of particles and forces. The most dramatic explanation for the excess is the brief appearance in each collision of a long-sought particle called a leptoquark, which would bridge the two known families of particles. But the researchers caution that the excess could still be a statistical fluke.
