| ABSTRACT: |
The Standard Model provides remarkably precise predictions for the dependence of the strength of parity violating weak interactions on the energy-momentum scale. Any significant deviation from these predictions therefore gives us a glimpse into the world of new physics, long believed to exist beyond the Standard Model. We discuss the current status of the tests of the Standard Model predictions. This includes an outline of what has been achieved at JLab. However, the focus is on recent developments concerning the measurements of neutrino deep inelastic scattering at Fermilab, which have provided the major evidence of possible new physics concerning the measurements of neutrino deep inelastic scattering at Fermilab, which have provided the major evidence of possible new physics in this area in the past decade. We shall see that fundamental discoveries concerning charge symmetry violation in parton distributions as well as a novel feature of nuclear structure functions resolve this long-standing anomaly. |
