1. The Intensity Frontier at CSS2013 J.Hewett, H.Weerts for the Intensity Frontier groups July 29, 2013 Introductory talk at CSS2013 at the University of Minnesota

2. CSS2013; Intensity Frontier Intro; July 29, 2013, H.Weerts 2 Develop a coherent and interconnected view of the Intensity Frontier for CSS2013. Describe future facilities and experiments at the Intensity Frontier and their capabilities. Document the contributions of the Intensity Frontier towards addressing the major questions in particle physics and explain how and why it is complementary to the other frontiers, which together constitute experimental particle physics. Charge for the Intensity Frontier workshop in April 2013: Written a while ago……still valid for CSS2013

Explain physics potential and opportunities with this set of experiments What is your (audience) job this week ? What is your (audience)/our job after this week ? Ask your questions; get to know & understand the goals of Intensity Frontier experiments and the science addressed by them Be able to explain ( within and outside the field ) the role of the Intensity Frontier experiments as part of the HEP program. How they fit into the spectrum of science addressed by HEP. We as a community can speak in a positive way about the whole (all frontiers) and fascinating science spectrum of HEP Our goal:
