EP Seminar
Statistical Issues in Searches for New Physics

Europe/Zurich
503/1-001 - Council Chamber (CERN)
Description
Given the cost, both financial and even more importantly in terms of human effort, in building High Energy Physics accelerators and detectors and running them, it is important to use good statistical techniques in analysing data. This talk covers some of the statistical issues that arise in searches for New Physics. They include topics such as:
- Should we insist on the 5 sigma criterion for discovery claims?
- What are the relative merits of a Raster Scan or a "2-D" approach?
- P(A|B) is not the same as P(B|A)
- The meaning of p-values
- Example of a problematic likelihood
- What is Wilks Theorem and when does it not apply?
- How should we deal with the "Look Elsewhere Effect"?
- Dealing with systematics such as background parametrisation
- Coverage: What is it and does my method have the correct coverage?
- The use of p0 vs. p1 plots
