"The Weinberg Angle and Possible New Physics Beyond the Standard Model"*

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 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.

Upcoming Physics Seminars:

Nov. 12 - Jenny Thomas (University College London)
Nov. 20 - Jacques Soffer (Temple University)
