9. August 6, 2007NuFact 07 - PPEG9 Physics performance evaluation The main purpose of the PPEG is to evaluate the physics performance of a given experimental setup (neutrino factory or other, existing or planned) in a transparent, consistent and documented fashion. The main purpose of the PPEG is to evaluate the physics performance of a given experimental setup (neutrino factory or other, existing or planned) in a transparent, consistent and documented fashion. Transparent: Clearly state Transparent: Clearly state –Definition of performance indicator –Approximations used –Chosen input parameters, luminosity etc. –Confidence level –Treatment of systematics Consistent: Assumptions should be on equal footing Consistent: Assumptions should be on equal footing Documented: Relevant information will be archived and will be accessible. Use of a website. Documented: Relevant information will be archived and will be accessible. Use of a website.
