Luminosity Overview

This topic covers the issues related to understanding the luminosity delivered at the interaction point. In addition to the instantaneous and total integrated luminosity, many physics analyses also require a detailed understanding of the differential luminosity spectrum (dL/dE) resulting mainly from the large beam-beam interactions in the collision process. All foreseen measurements of particle masses, for example, are highly sensitive to the exact shape of this luminosity spectrum. Methods for optimizing the delivered luminosity will also be considered in this topic, due to the significant overlap in required instrumentation.

The following is a list of topics and questions which is almost certainly incomplete. Please feel free to suggest additional questions, provide answers, or express an interest in thinking about any of these issues.
