Departmental Colloquium


Neutrinos and the End of Particle Physics

Kevin Graham
SNO

Time
 
Tue. October 25, 2005     11:30 AM     Stirling A

Abstract
 

The impressive agreement between the standard model of particle physics and a vast array of experimental results has led some to suggest that we are nearing the end of particles physics research. During the last five years, however, results from neutrino experiments, including solar neutrino measurements from the Sudbury Neutrino Observatory (SNO), have demonstrated that our understanding of fundamental particles and their interactions is certainly not complete.

A brief introduction to particle physics will be provided. A summary of the main open questions in the field will be given with emphasis placed on the role of neutrinos in answering those questions.

The SNO detector and calibration procedures will be described in detail along with presentation of the latest physics results from the complete salt-phase data set. The impact of these results will be discussed in the context of neutrino models and the standard solar model.

The final portion of the talk will describe ongoing work towards the realization of a liquid scintillator neutrino experiment (SNO+) utilizing the existing SNO apparatus. The technical challenges and physics potential of the SNO+ will be presented.

Refreshments will be available after the talk. Kevin Graham is one of the short-listed candidates for the recently-advertised Tier II Canada Research Chair in Particle Astrophysics.
