Under construction

This chapter introduces you to the general dataflow from the CMS detectors to the final analysis.

The first section describes the generation of Monte Carlo samples which on one hand are used to represent the real data before the experiment starts and which on the other hand will be used to compare with the real collision data when the data taking has started.

The following section describes the online selection procedure which defines the part of the collision data to be recorded, and the division of the collision data to the primary datasets. It also explains how part of the event data in the primary datasets can be accessed through skimming jobs.

The last section gives general guidelines on analysis methods.
