The Nobel Prize in physics has been awarded to theorists Peter Higgs and Francois Englert to recognize their work developing the theory of what is now known as the Higgs field. U.S. scientists played a significant role in advancing their theory and confirming it with the discovery of the Higgs boson.

Three theoretical physicists have taken an important step toward eliminating theoretical ambiguities from the staggeringly complicated mathematics used to explore the interactions of quarks, the tiniest known bits of matter inside protons and neutrons, and gluons, the enigmatic particles responsible for keeping them trapped there.

Scientists analyzing data from theScientists analyzing data from the BaBar experiment, which operated at SLAC between 1999 and 2008, recently published the results of a search for signs of invisible particles: exotic bits of matter that interact so weakly with ordinary stuff they left no mark in the BaBar detector.
