The 12 GeV Upgrade is a unique opportunity for the nuclear physics community to expand its reaches into unknown scientific areas. For the first time, researchers will be able to probe the quark and gluon structure of strongly interacting systems to determine whether QCD (quantum chromodynamics), the theory believed to describe strong interactions, gives a full and complete description of hadronic (3 quark) systems. Jefferson Lab at 12 GeV will make profound contributions to the study of hadronic matter-the matter that makes up everything in the world.
An international collaboration of scientists working at Jefferson Lab has completed a new precision measurement of parity-violating electron scattering on the proton at very low Q2 and forward angles to challenge predictions of the Standard Model and search for new physics.
