Statistics in HEP: Theory and Practice — •Jochen Ott — Universität Hamburg, Hamburg, Germany

Statistics plays a crucial role for the interpretation of analyses in HEP. While the mathematical principles of the statistical methods are known for many decades, their application to problems in HEP requires some adaptions.

This talk introduces important statistical methods in theory and discusses their application in realistic problems as they appear in many LHC analyses. In particular, this includes model building, interpretation and handling of systematic uncertainties, and approximate methods.

The application of statistical methods to problems with a large number of systematic uncertainties and channels can lead to numerical instabilities and long turn-around times, which impedes reproducibility and re-evaluation with different assumptions. These challenges are addressed by the fast and robust framework theta, which has been developed by the speaker.
