Recent Electro-weak News from the Neutrino World

Dr. Jaehoon Yu

Neutrino-nucleon scattering experiments have been used

 to probe the structure inside nucleons.   In addition, since

 neutrinos interact only through weak forces, they probe

 the character of this interaction separate from the other forces.

 In this talk, I will be presenting the latest result in this

 area of investigation from the NuTeV experiment at
 Fermilab's fixed target program.   The new result in the

 weak mixing angle measurements deviates from theoretical

 prediction by about 3 standard deviations, prompting possibilities

 of many new interpretations.
